Ping.fm is a simple service that makes updating your social networks a snap. Update from anywhere using AIM, GTalk, iGoogle, WAP, iPhone, SMS and E-mail. It works with systems like Myspace, Linkedin, Blogger, hi5, Facebook, twitter and so on. It's a sensible idea for those people who post/comment in different places and find it hard to keep up, though of course it does mean that if your friends are in the same places they'll see the same message multiple times!
Twitter Groups allows you to tag your followers into different groups. Then you can
send a message to those groups without needing to send the message to
each person one at a time!
