My friend and I have a site (www.rosasecta.com). It uses a lot of Ajax, but it's all by hand, and it's really ugly and hard to dig through. We want to switch to a JS library, but JQuery, Prototype, and Dojo are to large. We just want a small, compact library that can do AJAX cleanly and some basic DOM selecters. Can anybody recommend one...
