Blog sub forum - a good subforum for Web Development forum
Codemaster - Nah... some of the programming code doesn't related to web.
Arts & Design - Same... half of it might not related to web.

Maybe some others will suggest...
Software - nothing much, same. Half of the software doesn't concern on web development.

ZZzzz correct me if i wrong eh.

My suggestion is, if you want to have a web development on specific issue, maybe can head to the particular forum and ask. Generals idea is far more better than specific only. (Tell me I'm wrong , if I do.)
