A new Lifestream plugin was released a few weeks ago simply called “Lifestream”. It’s written by David Cramer. He apparently began using the RSS Stream Lifestreaming plugin and decided to roll his own version shortly after. You can view it in action on his site here.
RSS Stream is a great plugin and this one just takes it a step further by using the SimplePie parser and offering more flexibility in the feeds it can use. Keep in mind that it requires WordPress 2.5 minimum and PHP5 which may not be supported by your hosting provider.
