Guilty. Every project, I use jQuery because it’s easy. Thomas Fuchs gently notes the foolishness of embedding a hefty, do-it-all framework when a tiny framework optimized for the specific needs of the site or application would be more appropriate. I’d love to see a comprehensive list of these micro-frameworks.
One benefit of monolithic frameworks is internal consistency. Hopefully micro-frameworks can replicate that. Alternatively, the larger frameworks should start taking steps to break themselves into chunks available for optional inclusion.1
Update: Thomas put together the directory about the same time this post went live. Check it out.
