What I love is he gets railed on this thread but no one said squat on his [WoW] WoWMultiVids: Setting up Keyclone! Part 1 and part 2.
video thread...

He does have a single affiliate link on his blog, no advertisements though, so it's obviously not driven around the idea of earning money with the site... he also has links to KeyClone on his site...

I've seen him asked to tone down the links to his site by Ellay and from what I can tell he's done as asked.

As for the youtube subscribers, is there a way to earn money with YouTube? Last I checked it's just digital fame, not fortune. The keywords are moderately relevant, not the way I'd promote the videos myself, but not against any rules of youtube or this site...

I dunno, I see some pretty well made videos that help people out, and community members railing a guy who's just excited about our hobby. Vyndree and Suvega didn't get any grief over promoting wemultibox.com here, and its a LOT more of a competitive site than this guys blog (of course I'd wager they got Ellays permission up front as well.)
