The latest “lifestream aggregator” to hit is this thing called Plurk.
plurk.com
It appears to be similar to Twitter in scope. Micro-blogging like “I just ate cake” or “I’m headed to the bathroom to pinch one” etc…
Plurk seems to come pre-rolled with a handy Plurk widget for your blog.

I purposely captured this image from Duncan Riley’s blog just to bug Avatar. Watch the comments for a response from Avatar.
I see that the widget not only shows what you have written…but also links to the responses to your statement, question…or whatever.
It also appears as though there is some type of sharing ability. Sharing of what I’m not sure.
This is a JavaScript widget and as such limits some users placement.
