Uzbl isn't really written in one language. uzbl-core (the Webkit wrapper) is written in C, the event-processing framework and tabbed-browsing wrapper are written in Python, and much of the functionality is handled by external scripts written in sh and javascript. The difference has nothing to do with the language; hbro is taking a very different approach to configuration and integration. (e.g. uzbl does IPC using FIFOs and sockets; hbro is using ZeroMQ. uzbl is extensible with external scripts; hbro seems to be extensible using Haskell.) (I'm the maintainer of uzbl. k0ral used to be involved with uzbl, and I'm sure hbro has learned from uzbl's mistakes.)
