I'm signed up!

You already know that you can interact with Twitter at our web site or by texting from your mobile phone but now you can use IM to do everything that you can do over SMS. This is good when you're working on your computer and you don't want to visit Twitter.com or start sending and receiving SMS. IM is always there and easy but it's a little less demanding of your attention.

Today we added more to the You can download it from our API page.

Now you can create a free Twitter account without giving us a phone number. Previously we were asking for a phone number up front but user testing showed that some folks wanted to sign up and kick the tires first.

So if you haven't joined Twitter yet, head on over and sign up with just an email address. You won't be able to take advantage of all the fun mobile texting features of Twitter until you decide to input your number in Settings but you can still do lots of stuff.

With Web-only Twitter You Can Still:
• Update your Twitter timeline on the web
• Place a Twitter Badge on your MySpace or blog
• Let friends receive your web updates via their mobiles
• Send direct texts from the web to individual friends
• Upload your profile pic and link to your home page
• Invite friends by email or phone number

Even though we did a lot of behind the scenes type stuff, that's today's major update. Come on over and try out Twitter if you haven't already.

In case your not subscribed to receive Twitter email from us from time to time, here's the text of an email I sent out earlier today.

There have been some updates in the world of Twitter that we wanted to let you know about. Some of them are geeky, some of them are funny, and at least one of them is straight-up useful. If you haven't been around in a while, come visit

That's about it for now. We're busy on some big improvements and feature updates but those will have to wait until next time.

Mobitopia a Twitter friend, you will get a "mobile link of the day" texted to you so you can check it out. If you've got a Treo or some type of phone like that, there are links in in the SMS text that you can click with your stylus.
