I'm going to go against the grain and say .com is far nicer to read in terms of colour. Maybe .org looks better in a productivity environment, but Relic knows their audience - evening gamers who don't want to bathe in the light of 1000 suns.
Heh, my original design for coh2.org was light text on dark backgrounds, and it got shot down pretty hard. It would be cool to have a reverse skin (a "turn off the lights!") for coh2.org but it would actually be a ton of work to create and we're always busy with other priorities.
Big images look great on the official site:

but I have the same problems that others have already mentioned -- the "create post" editor is clunky and buggy. Making those posts (embedding images, trying to add links, trying to embed a video, trying to format the text) is an absolute nightmare. Sometimes I try to make a post and just get so frustrated with the editor that I eventually give up and abort the post entirely.
