There's a couple of social tools I've fallen in love with over the last month or so.
Twitter is horribly addictive. It allows you update your friends with quick updates as to what you're doing via text message, IM or the Twitter website. It doesn't sound like much, but just try it. It's fascinating getting these small, regular updates about other people's lives. My latest Twitters appear at the top of the sidebar of this blog's homepage, and you can subscribe to my updates over at my Twitter page.
The other tool that's caught my attention is MyBlogLog, which is a fascinating way of keeping track of who's visiting your site and of finding interesting new blogs as well. You can see my MyBlogLog box on my blog's frontpage. I'm not the only one who thinks it's a great idea, either. Yahoo has snapped the service up, and Om Malik has a good anatomy of the deal.
