Jeremy Keith recently unveiled his lifestream, a slick yet very simple aggregation of various bits of his online presence.
Chris Davis liked the idea so much he went and implemented his own lifestream by hacking up a WordPress plugin — especially nice for those without much control over their hosting environment.
It seems to me that lifestreaming is clearly a job for Planet Venus. Basically, a lifestream is “Planet Me,” and Planet Venus is the awesomest planet engine out there. So I went ahead and hacked one up for myself. It's an aggregation of my activity on this blog, del.icio.us, Eventful, Flickr, LiveJournal, reddit, twitter, and wordie. Enjoy!
