James Buck's timely use of Twitter. Send it to your loved ones.

Digital Garage engineer Yuu Takaki took this short video at the Twitter office when he was here helping us create Twitter Japan. We are each saying, "Welcome" in Japanese. (At least that's what Yuu told us it meant!)

We're live in Japan!

We’ve noticed a significant percent of Twitter usage consistently originating from Japan despite the fact that our service is in English. This highlighted an opportunity for us to make Twitter better so we worked with our partner, Digital Garage to launch a partnership agreement we have with Digital Garage also includes some commercial experimentation in the Japanese market through it’s subsidiary, CGM Marketing, Inc. At launch, visitors to Twitter.jp will see media from two clients. One is a new book about Twitter being released in Japan, another is an automotive news service built on Twitter and sponsored by Toyota.

We're excited to announce two recent hires. Steve Jenson is a familiar face for a few of us here at Twitter HQ because he's a former Google software engineer known for his work scaling Blogger and Blogspot—a service which tens of millions of people use on a regular basis.

Join us in welcoming these two superstars to the Twitter team. They are already digging in, getting up to speed, and helping us make Twitter better. Good things to come.

On Friday, we successfully deployed a new memcache project as part of our overall work to create a more scalable service. After the deploy, we needed to move a lot of data with minimum impact on service quality. To do this, we put together some code that moves data only as it is requested.

This process kept a minimum on service disruption but did cause Twitter to have a complex conversation with two sets of caches over the weekend and into today. This resulted in some caching issues—namely, the /home timeline cache wasn't being updated correctly for everyone.

We're aware of this, we realize that it's annoying, and we're meeting today about how to best finish up this project and clean up any remaining bugs. Thanks to everyone who checked in with us on Satisfaction, @replies, and email over the weekend. Overall, completing this memcache project is a big win that will lead to increased stability.

Update: We're working on this project more today and will be checking in again this evening. Also, we keep folks updated as much as possible on our forum over at Get Satisfaction (in case you're only visiting this blog for news).

Update: We've deployed code that gets Twitter talking to one - and only one - pool
of memcache servers. This eliminates a lot of potential confusion and is progress. But we are still noticing related symptoms so we're still investigating and making improvements.

Update: Okay, here's a more satisfying update. We're catching up on things and backfilling the timelines. Once things are caught up, we should be good—and successfully moved to the new memcaching scheme.

U.C. Berkeley student's Twitter messages alerted world to his arrest in Egypt: "When Egyptian police scooped up UC Berkeley graduate journalism student James Karl Buck, who was photographing a noisy demonstration, and dumped him in a jail cell last week, they didn't count on Twitter."

read about the integration on their site. But it's pretty simple:

1. Follow the Twitter user ChaCha
2. Send your question as an @ reply (e.g. "@chacha Does it matter if the soil is wet or dry before re-potting a houseplant?")
3. A couple minutes later you'll get your answer ("@goldman Let the pot go dry. With your fist, bang the bottom of the old pot and the plant, root ball and all, will come out intact.")

Good times.

Totally starred it. Those guys are good.

And following on from yesterdays post: we've made another minor change to the web UI. If you log in, you'll find a new tab is available - the "everyone" tab.

The "everyone" tab is basically what we referred to previously as the public timeline. We've moved it down to sit next to your other tabs so that you can keep track of what everyone else on Twitter is saying, making it easier for you to find other interesting people to follow, as well as giving you access to the public timeline without taking you away from your ability to create an update or your sidebar.

You may also have noticed that we briefly had a link to a simple survey where we asked you what you thought about Twitter. We've taken it down now as it's fair to say we were inundated with responses! Thanks to everyone who took part, and we'll try to share the results soon.

Last night, we rolled out a few minor tweaks to the web UI which should hopefully make your experience with that part of Twitter a little better. Here's a list of the things that we changed, and why we changed them.

1. Search is now at the top of the page

There's also a new version of the page that people will see when they view your profile page when they're not signed in. Since this page is often indexed by Google, we wanted to make sure that new users could quickly see what Twitter was and what it could do, and provide a nice big button for them to join with.

4. Other "fit and finish" details

Finally, there are a few things that we've tidied up around the site - we've added tabs to the settings page to be more consistent, we've moved the sleep setting for your phone over to the devices page rather than having it on a separate page, we've added an email invites box to the bottom of the search results in case you don't find who you're looking for, we've made the link to the page where we offer badges more prominent (look out for new ones soon!), and we've added a link to a survey so that we can find out a little bit more about you (this will only be temporary, so if you want to participate, make sure you do now).

This is the first step in our current effort to clean up a few areas of the site that we know need some work. We have a few more fixes to make in the near future (also for SMS and m.twitter.com) before we get on to the exciting new features we have planned for the rest of the year!

We hope the changes make a difference to you and, as ever, we'd love to hear your feedback.

Twitterholics is a blog covering many of the great new applications and extensions of Twitter. It's amazing how much cool stuff is being built.

Washington Post reported that Twhirl has been acquired by online video company, Seesmic. WaPo reports, "Twhirl creator Marco Kaiser will be joining Seesmic. The service will remain free to use."

Living in the Bay Area, we have noticed that we reach for our phones to Twitter the second we feel an earthquake. It looks like Anne Jackson has discovered that Twitter to see the flow of conversation around certain topics. It happens that I’ve been tracking CNN and tornado for a while. Little did I know that these two tracks would seem to merge. With last night’s tornado rolling through downtown Atlanta the play by play, via Twitter.
