For people like me who find enlive/hiccup/stencil (template libraries) inappropriate for web development that involves more than one person I would beseech them to take notice of:
Things like caching, extensive testing and benchmarking in a production environment, and differentiating dev vs. production behaviors are the most apparent right now. There could be others, I haven't spoken with Steve in IRC about it.

That's all I have to say about Clojure web dev for now. It's good to know that people are shifting to a more modular approach now.
