The cheesier the better!
Not always, but often, I've noticed that when someone makes a well thought out, intelligent, well written post, it tends to sit. No replies, no thumbs up...nothing.
At the top of the thread, most votes and responses go to the insincere, cheesy cliché. The smartass with a one-liner that's usually lame and predictable.
I love a good, off handed remark if it's well thought out and original, but that's seldom it. is it normal users pride themselves on above average intelligence, but to an outsider coming in and reading, it wouldn't appear so.
