Google Sidewiki

Google Sidewiki seems like a nice way to post graffiti like comments on Planet Lotus throughout the day. I've gone ahead and posted a note to get things started. If you're new to sidewiki here is the first article I found on it while looking up the date it was launched; Sept 23rd.

Not sure how I stumbled across this tonight but its odd. All week I've been wanting to do something similar to PL after figuring out how to use Twitter OAuth for TwunLog.com, it would be nice to have an ajax like way to post small comments about posts on the PL main page.

So I'm curious, is anyone else using sidewiki?
