Who are the two mysterious Thumb people?

Damn! Why didn't I think of that?

I thumb down this guy more than a couple of times. Thankfully my degree of stupidity is not infinite and I decided to save energy and put him on ignore. ...now I don't have to read his junk and thumb it down. I went the efficient route and saved some thumb energy.

i rarely if ever thumb, i can't say for sure i've never thumbed down, but you could probably count the times using the thumbs of both hands

it would be great if like the likes on facebook, the thumbs were linked to the thumber

That is brilliant!
