How to, showcase one specific catagory on the main page.

Hi,

I’m new-ish to word press and loving it! Please check out my site here:

Most of my blogs are pretty visual. In that they incorporate images and or animated/video clips.

My question, Is there a setting in wordpress that alows you to control which catagories are displayed in the main blog time line? If not does anyone know of a plug in that could control this?

The reason I ask is that I’d like to be able to post more ‘technical content’ in my blog… however I’m a ‘creative type’ and I deal with a lot of other creative types in my busniess and wouldn’t want to bog down first time visitors to my blogs with a bunch of extra tech entries…

thanks
John Chalfant
