Out of the ~10 I’ve just clicked, ~8 took me to ‘for sale’ threads, as I expected.
Makes sense, cos sellers are bound to tag their adverts carefully but it leads me to think, as I suspected anyway, that the tags window at the top of chat threads is really only useful as a place to make anonymous comments on the discussion.
Most of the tags I’ve seen are hardly useful from a search or metadata point of view. It’s more like graffiti; "Dorset Knob = Knob", for instance.
I think they’re quite funny, and I’d be interested to see the tag cloud from the chat forum only, with tags from For Sale threads ignored.
