If you ask me the site has become "too big" - in terms of number of articles and categories etc. It is hard to navigate and to know what kind of content is available - and where it is.
Therefore I have now started to create subsites and move some content out to those instead. Here's my ideas on how to split the content:
ASPCode.net - asp/asp.net scripts and articles
Programmingado.net - database related articles
AjaxAndASP.net - asp.net and Microsoft Ajax
I have already started to move some content out and will continue to do so in the days to follow.
