I just joined posterous. Social networking has just taken another leap and if you can't fight it, I suppose the next best thing to do is join 'em. Well, it might not be just another phase. Check out: http://wormhole.posterous.com
Subscribe if you want to be notified when there are postings there. Start your own posterous micro-blogging site; it is really simple. Just add them to your address book and register after you send your first mail. Search for topics you want to have something to say about and you will find plenty to do on posterous. I'm still not sure about twitter, but apparently just about everyone who is social networking is using it. No wonder mailing lists and the old way to do business and socializing is just that: old.
