Those are really good points, thanks!

I'll try to just get going and pick a lang for that. Web-dev intimidates me, cause I should know HTML/CSS+JS for front-end, and SQL+{ruby|python|clojure|haskell|php|...} for back-end. That's why I was thinking about going w/ sth like clojure/ruby, cause that takes care of front-end as well. But what do I know?
