Keep in mind, both uoguide and uostuff were player projects, hosted by, and the web design done by 2 different players. The person who created and supported uostuff quit the game, and rather than just pulling the plug, offered the content to the person maintaining uoguide.
I agree, the uostuff site functioned MUCH better in terms of locating information as a knowledge base. It was a straightforward search engine presentation, and the articles simple and easy to navigate, and appeared to be a quick and easy to use wiki in terms of adding and finding info, which is what you want in a wiki.
Perhaps uoguide will improve as it absorbs the considerable info that was contained on uostuff. JCtheBuilder seems pretty open to feedback concerning his site, perhaps you could PM him some suggestions on what you think would make the site more functional. (He requested such feedback in a thread when he began the project from what I recall).
