Anyone checked out http://wordle.net/
If you enter a URL or some text it will analyse the thing and create a sweet looking word cloud that may or may not be interesting. Doesn't work that well on moblog (only analyses your most recent post) and certainly doesn't work too well on new or less wordy blogs (like mine here, of my http://stolenlight.wordpress.com/
blog). Worth a quick look though. Your blog cloud was quite pretty, Alf. Check it.
