I create my own customizations for the forums (among other sites) and thought I'd share them. Currently only supports Firefox 4, but if you're interested: http://userstyles.org/styles/46673/cnet-forums-clean-and-wide
If you do try it out, let me know what you think.
Everyone has an opinion.
If Cnet wants to turn their site into "twitter for twits" that's their business.
Leave the forums set to Adult mode.......plain vanilla.
Start with the ability to read and post.....anything else is an extra.
Keep the extras to a bare minimum.
