No sooner had I signed up for Twitter finally, than Stowe Boyd pointed the way to Jaiku . This seems more complete - you can actually include anything with an RSS feed - Flickr, Twitter, del.icio.us, your blog, last.fm ... so it gives a much broader view of your Web presence, or "lifestream", as Boyd phrased it. The really sweet thing is that you can have comments on anything streamed through Jaiku (is this a meta-community - comments on comments?).
