See below for an update.

One year ago, we posted "Your Account Settings.

One of our core values as a company is to defend and respect each user’s voice. We try to keep content up wherever and whenever we can, and we will be transparent with users when we can't. The Tweets must continue to flow.

Update - Jan 27, 2:20pm.
Since yesterday’s post, we’ve gotten a number of questions that we’d like to broadly address with this update.

In short, we believe the new, more granular approach to withheld content is a good thing for freedom of expression, transparency, accountability— and for our users. Besides allowing us to keep Tweets available in more places, it also allows users to see whether we are living up to our freedom of expression ideal.

Q: Do you filter out certain Tweets before they appear on Twitter?
A: No. Our users now send a billion Tweets every four days—filtering is neither desirable nor realistic. With this new feature, we are going to be reactive only: that is, we will withhold specific content only when required to do so in response to what we believe to be a valid and applicable legal request.

As we do today, we will evaluate each request before taking any action. Any content we do withhold in response to such a request is clearly identified to users in that country as being withheld. And we are now able to make that content available to users in the rest of the world.

Q: What will people see if content is withheld?
A: If people are located in a country where a Tweet or account has been withheld and they try to view it, they will see a alert box that says “Tweet withheld” or “@Username withheld” in place of the affected Tweet or account.

Q: Why did you take this approach, and why now?
A: There’s no magic to the timing of this feature. We’ve been working to reduce the scope of withholding, while increasing transparency, for a while. We have users all over the world and wanted to find a way to deal with requests in the least restrictive way.

Hack Week is one of the ways we actively promote innovation through experimentation around the company. This week, a wide range of folks here are taking time away from their day-to-day work to collaborate and develop ideas that they are passionate about.

Get comfortable with uncertainty; it leaves room for inspiration.

Beginning today, right-to-left languages are now available for volunteers to translate in the Twitter Translation Center, starting with Arabic, Farsi, Hebrew and Urdu. The Twitter Translation Center takes a crowd-sourced approach to translating and localizing Twitter for people around the world. More than 425,000 volunteers contribute to the Translation Center, and to date have helped make Twitter available in 22 languages. With their help, these will be the next four.

As we prepare to add Arabic, Farsi, Hebrew and Urdu to Twitter, we’ve developed new ways to ensure that Tweets and hashtags will work properly in right-to-left languages. We’ve also made changes behind the scenes to give right-to-left language speakers a localized user experience. As soon as our volunteers have completed their translation work, we’ll make Arabic, Farsi, Hebrew and Urdu available for everyone on Twitter.com later this spring.

Every year, the President of the United States delivers a kind of “status update” and his proposals for new initiatives to a joint session of Congress. In the early days, it was a private communique between two branches of government; today it’s very much a public event to which millions of Americans, as well as people around the world, tune in.

Every year at this time, film buffs from around the world converge on Park City, Utah to see more than 200 documentaries, dramas and short films at the list of all the filmmakers at this year’s festival; you can join the conversation by sharing your opinions and comments using the hashtag #Sundance.

Throughout the festival, keep track of guest Tweeters like screenwriter and director @MichaelMohan (“Save The Date”), hip-hop artist and actor @Common (“LUV”) and comedian-turned-screenwriter/director @Birbigs (Mike Birbiglia, “Sleepwalk With Me”). From A-list directors like @SpikeLee (“Red Hook Summer”) to New York Times film critic @aoscott, you can tune into any perspective about what’s happening.

You can even go behind the scenes as Sundance directors talk about their films. Watch @aliklay describe her documentary about Chinese artist and activist Ai Weiwei, and visit the @sundancefest profile page for more filmmaker videos.

Tonight, the remaining field of Republican candidates took to the stage in South Carolina to make their case to voters. Throughout the debate, Fox News encouraged viewers to rate each candidate’s responses in real time by tweeting #answer or #dodge plus the candidate’s name.

From Mass Relevance to track the #answer and #dodge data. The tweeting was immediate, providing a rich real-time picture of audience reaction to each candidate’s answer within 15 to 30 seconds. Here are a few of the debate highlights:

Newt Gingrich
After a slow start and a net #dodge rating for an answer on his recent attacks on Ron Paul saw his most significant number of #dodge votes in answers around foreign policy.

As the primaries roll on, so do the political conversations on Twitter. If you want to be the first to hear what’s happening on the campaign trail as it unfolds in real time, here’s a through this before — so here’s a reminder of how you can have your say:

• When a candidate answers a question, tweet that person’s name with #answer (if you think they answered the question) or #dodge (if you think they, well, dodged it).

• Watch the live results at live.foxnews.com.

To further join the conversation, include the debate’s official hashtag (#scdebate) in your Tweets, or search for that hashtag on Twitter.com to see what everyone else is saying.

More than 400,000 volunteers have contributed to our change your language setting.

Tweets have become one of the most important — and simplest — ways for people to share news, humor, inspiration, and knowledge online. And they are even richer when they include pictures, videos, locations, or links to other sites on the web. With the new version of Twitter, anyone can embed Tweets simply by copying and pasting one line of code into their website. Embedded Tweets automatically open to show images, conversations and videos.

Whenever you see a Tweet embedded in a web page, you can follow that user with a single click and reply, retweet or favorite the Tweet right from the page. Click on the author’s @username to see their Twitter profile page, or click the date in the lower left corner of the Tweet to see Replies, Retweets and Favorites on the Details page. Try it now on this embedded Tweet.

People are already embedding Tweets across the web in order to continue the conversations that matter to them. U.S. Senator Patty Murray (D-WA) embedded a Tweet how you can embed Tweets on your own site, and watch for them on your favorite websites.
