Ask HN: What's the next step learning Clojure?

I have been enjoying learning Clojure but have come up against a wall of too many choices.

So far I have read several of the "introduction to clojure" websites and worked through most of the first page of Project Euler puzzles on the first page. I've read the unfinished SICP in clojure: (http://sicpinclojure.com/?q=sicp/5-1-1-language-describing-register-machines) and through half of the unfinished ebook of "The Joy of Clojure" (dead tree version just shipped :) )

What I would like to do now is to try writing some kind of web app. But here I am intimidated. I am not a Java programmer and many of the "getting started with clojure" articles I have found loose me by assuming I know how to set up Java webapps.

Also, should I use Google App Engine? Some other framework/hosting? I guess I am probably fairly unique in that I want to learn about making webapps through clojure rather than knowing about webapps and trying to apply the lens of clojure to that knowledge. I am excited to learn about tools or frameworks or even other languages that would complement clojure web development, but I feel like I don't know what I don't know, and don't know what I should be reading about and experimenting with.

Thanks in advance!
