I found their website a month or so ago and have been using it quite a bit since than (maybe too much). It's quite helpful and easy.
It's a javascript framework thats easy to use and makes things like Ajax, Json, CSS effects and just generally managing your elements a hell of a lot easy and faster, plus its cross-browser. I mainly use if for the effects. They have some demos on their site, here, if you want to see what I mean. Or you can check the effects on my site (I had to plug my site at some point...
So anyone else used it? Anyone else have an opinion on it? Anyone else think I have used to many effects on my site?
