A powerful lifestreaming plugin which provides a historical views of your activities online by aggregating it from any service you use.
I would not suggest you put it in your sidebar for now. Depending on how many feeds you've used and the items in them, the first run (before the simplepie cache takes over) might take 10 or more seconds.
In order to utilize the cache, make sure you have a
wp-content/cache folder that is writable (755). See here
Just check the Lifestream blog explanation explanation.
Patches are welcome ;)
