I found How to choose a JavaScript framework » d’bug (via Ajaxian). In it the author brings up several things to consider when evaluating a framework.
It’s somewhat related to my earlier post on looking for a comparison of JavaScript frameworks, and his was posted just a day before mine.
It’s not the comparison table I was looking for, but if I ever get around to making that table I’ll certainly use some of the points mentioned in it. I think most of the article could apply to any framework developer tool, not just JavaScript frameworks.
