It is not just the weird sizing, it is the inconsistent sizing, even on the same page. Look at the Trending Threads page and tell me something isn't messed up. The thread titles are huge but the forum directory is barely readable on any sort of high res monitor. Just make them one or the other so we can at least zoom in or out to compensate evenly.

Also please don't forget about the sub-forum headers. Thread/Original Poster, Sticky Threads and Normal Threads should not be the same size as thread titles and definitely shouldn't be smaller than the actual sub-forum header. Either make them larger or put them in a contrasting cell. I'm on a calibrated monitor and even I can barely tell that those cells are slightly off-white. Even the Fodors forum, an IB joint, at least has the courtesy to have a contrasting color for sub-forum headers.

Fix those two things and I'll call it a win.
