Twitter IM access has been down for me for a while now. Because of this I have started using jaiku more. Something I really like about jaiku is that it has an IRC feel to it. You can create channels for users to follow. This works the same way as following a user. When you want to post to a channel just preface it with a #. So for instance if I wanted to tell everyone following the Foresight jaiku channel something I could do “#foresight packaging some cool new app for everyone.”. Anyone following that channel would get the update. There are lots of channels already created too. I looked and I have seen quite a few for Ubuntu already. If a channel does not exist yet then it is very easy to create it.
You can follow me (if you want) at http://etank.jaiku.com/. If you do not have a jaiku account then let me know. I currently have 19 invites left and I can send you one while supplies last.
