Here are some screenshots of what it looks like when running (completely unobtrusively, other than the appearance of these circles) on a Google search:
|Wikipedia is green but is it rated highly because it's given a fair account of this clinic and pointed out the concerns people have, or because it's a trusted web domain name on its own?|
Here's what Twitter looks like... Tom's post has a grey circle with a blue question mark by it, this just means that the site hasn't been rated yet. My own blog is pale green (compared with the darker green of CivilSociety's page in the last tweet) but I'm not sure if that's because someone has (or someones plural have) said that my blog is fairly trustworthy or that it gets a free-ish pass being a Google site.
You can create an account and leave comments about websites, which are visible to others who have WOT installed (as far as I can remember I've never commented on any of the MoreNiche websites but have been interested to see their ratings as given by other people). Charlie Brooker posted a tweet the other day that said "Cinemas that don't screen films properly should be marked w/graffiti to alert those who care. Like the Hobo code: http://bit.ly/qaeDim" and I think WOT has a touch of coding / alerting about it.
