Colleagues have noticed that in my spare time at work I've been "getting my geek on!" the definition being a vi window of code on one screen and google open in the other ;)
Linickx LifeStream will be a new WordPress plugin which allows you to life stream ANY feed. I've been having issues with FeedWordPress and to be honest it didn't really do what I wanted; now there are already may wordpress lifestream plug-ins, but mine will be different.
Difference 1: The plug-in isn't service dependant... i.e. you don't stream your twitter account or your LastFM account, you stream the feed. What this means is that when tomorrows-wizzy-new-service is launched you don't have to wait for me to update the plug-in. It also means you can stream odd stuff, such as I'm going to stream my commits to the WordPress plug-in repo ;)
Difference 2: No Requirements. The requirements for this are the same as the WordPress requirements. What this means is yes it works on PHP4 and no you don't need a separate installation of simplepie.
Difference 3: No Lifestream Pages, extra databases or tables. LifeStream feeds get created as "normal" WordPress posts, so if you digg something a post is created and you can do all the normal things like tag & categorize the post.
I'm in the process of finishing the package and installing the plug-in here on linickx.com but when it's ready you'll be able to...
