I have to agree in part with lifepower. There is just too many categories and spread too thin. Very few posts for many of the topics.

e.g.,
It is unclear how say "programming graphics" is different from "design creative"

I would rather see sub menus if you wanted to keep so many categories.

Here is a reasonable idea.

You should be able to see all the categories on one screen (1280x1024). Any longer and you have too many major topics.

At least that way you can quickly see where the new topics are.

A little while ago there was a discussion about scaring new users away. I still think too much emphasis on topics that do not interest the majority of visitors.
