Well I do have some feedback to give here:
1 - What I'd do is find out what sections of the site get used the most (not counting regular visitors such as myself, as over time we usually ignore the ads), then target the visitors that way.
2 - consider possible additional changes to the site. What would make more people want to visit motherboards.org? The more traffic, the more advertising income potential. Look at sites like anandtech.com who is extremely popular (despite a pretty closed minded staff when it comes to discussing opinions), Hardocp.com, Tomshardware.com (tho I like them less and less I visit there, they are popular), theinquirer.net, guru3d.com
3 - possibly adding a downloads section (yeah this would add to the cost, but can have specific sponsored links. Downloads such as useful utilities like CPUz, video drivers, tweaks, etc.
4 - more reviews! Computer nuts and people just needing computer/parts rely on reviews to help make a purchase decision. I want to know about what's the best for the money, and what's coming out; I'll bet I'm not the only one! I usually rely on many other sites for this. I'm hoping some day I can become a reviewer for a site as well.
5 - have a daily specials section hosted by one or more retailers. A few quick links on popular items.
There's a lot of stuff I have in mind that I know would work real well. Just by what I said, you really can't get the full picture. These changes would be small, one step at a time of course!
I've even had some crazy ideas such as adding models to a funny section, for a semi serious review. "Chicks and chips" "Hard drives and hard bodies"
I'm not good at programming of sites, but I'll gladly draw out what my ideas are like (the serious ones) if you want Mobocop, just let me know.
