I just so happen to be one of the top writers of all time over at eHow.com and I don't appreciate it being trashed like that. I met the entire company in person when they paid to fly me out to Santa Monica for their top writers get together. I used to be a quality moderator as well and yes, a lot of articles used to suck. They were mass produced garbage that someone pumped out to try and make money off volume. But those that sucked were either deleted in the mass deletion waves over the last year or didn't get linked to by anyone and are thus are buried on page 200 on google. My computer and tech articles on the other hand are great. They are straight to the point, detailed, and show step by step how to do something in a way that anyone can follow. They were all well reviewed and generally great pages to end up on.
Ehow recently closed their site to letting "just anyone" write and are routing new article solely through Demand Studios, which you basically need a resume to apply for and the entrance exam is brutal and denies like 95% of applicants. Almost all bad articles have been removed at this time and no articles are let on the site now without being reviewed. The entire moderation system was, at several points, shut down and basically marked as "all done." It's now, finally, a respectable source of information. Expert exchange on the other hand is a joke and the two should NOT be grouped together like that.
