My new lifestream blog is a "chronological aggregated view" of many of the things I do online. It automatically updates 24 hours a day with posts from my business site realestatezoo.com, my progressive community site bluesunbelt.com , my personal blog robwire.com, and dozens of sites that I use such as Del.icio.us, Digg, Magnolia, Reddit, BlueDot, Photos, Flickr, Youtube, Last.fm, Jaiku, Twitter, 43 Things, Wakoopa, ActiveRain, Flickr, Friendster, MySpace, Facebook, and various others.
