I have been reading about greasemonkey Firefox extension for quite a while, but (as probably most us) never bothered to install and test it. I suspect because the idea of chaning the page with a script in a browser is just too far out... It's really mind boggling, so read about it if you don't know what I'm talking about. Late last night I saw some list of favorite extensions and I decided to give greasemonkey a spin. And now I'm hooked. Altough I don't have a killer script idea (yet?) I'm totally in love with the idea.
I browsed the userscripts.org scripts directory and tried some Google enhancing scripts like Butler and Google Counter. I also tried to enhance Bloglines but nothing very useful in there. Last.fm (former AudioScrobbler) section also had some scripts but the most interesting was broken! Aha! Time to dig in the source code...
So I made a new version of Last.fm play statistics! - script that calculates tracks per week, day and hour and displays it beneath "Tracks played" in the profile. It's not my code, I just fixed what arvid wrote and latest last.fm HTML broke. My scripts list on userscripts now has 1 entry.
If you want to write your own scripts, Mark Pilgrim's Dive into Greasemonkey is the best way to start. His guide is really incredible.
