@Frank Apisa,
One can indeed vote down a thread. You go to the OP and click. I've done that occasionally for obviously racist threads.
I'm sure you're right about what I would call the "schoolyard I don't like you nyah nyah factor" especially when the humming begins, but I've been to too many threads where I can see just where the best contribution has been made ( ie~ when Oristar asks a question about idiomatic English and somebody writes a really good answer)
It doesn't take very many UPs to put the post on the top of most lists : 4 or 5 looks to be about average. It takes about four DOWNs for a post to disappear from view. About the same for a thread to do the same.
I wager that no one complains about their posts/threads being voted UP.
Again, it seems to me to be the easiest way to remove trollness from our midst at least temporarily, they are (those who actually are trolls) have that persistence you admire because they get so much sadistic pleasure from being anonymously public. That is something that sets you and Thomas and several others apart, you and the others who are not anonymous here, I think, deserve special applause.
I keep meaning to open to a new account wherein I would use my own name (that is my face up there on the left) but I never seem to get around to it.
Besides then, godknows who would show up at my building for a dinner on the roof?
