It is a rather strange thing to blog from your chat client. However, with IMified, you can. You can also have reminders, todo lists, post to Twitter (which Twitter already lets you do, but the service is down alot), and much more. I pretty impressed that you no longer need to actually visit the web to update your web presence.
As weird as it might sound, administering several different services through my chat client is pretty fun. Thanks to Tracy for pointing this service out to me.
