Clicking on a thread and reading it takes some effort. But if all I have to do is hover my mouse over the thread title and part of the OP appears as hovertext, that would be a lot more convenient. I'm pretty lazy and I'm sure I'm not the laziest person here. Just imagine how many threads go unread just because people are too lazy to click on it.
I'm trying to see things your way, but I can't put my head that far up my ass.
