In case you don't know what I'm talking about, ExpoTV.com is a video uploading website like Youtube, but specifically for product review videos. You sign-up and get a profile page, then you upload videos (you can review clothes, computers, laundry detergent, etc.), and I guess you get paid based on how popular your videos are. What I'm curious about is, has anyone tried to manipulate the site to get traffic back to your own website? On your profile page you get a nofollow link, but that's really it. I haven't seen any real public discussions about this, and I haven't noticed any videos on the site with sneaky promotion thrown in. Personally I haven't bothered to sign-up for an account yet, but someday I might investigate the possibilities.
