We've added couple of features in today.
The first is posting to twitter, which is available under a new button called "you".
Also you will see reply links on current twitter messages which link to it. To enable twitter posting you will have to give us your Twitter password (yes, really, Twitter don't support anything else) you can do this by going into the Twitter network page and clicking "settings". The you button also is quick way to get to your own stream and some other tabs will likely appear here soon.
Also now you can now view the stream for all your friends not just by interest level or by network as a few people have been asking for. The stream now tells you when the last big update was which is currently not more than every hour whilst you are logged in, we are working on backend improvements to make that more frequent.
Thats all for now, more new features coming soon, hopefully quicker than these ones were.
