The thing that I hate about the new layout is the thread listing... it takes up way too much real estate. I liked the old layout because I could click into the forum and quickly scan the threads to see if there was anything that I wanted to read... and dozens of threads were listed on a single page. It made efficient use of each line of text.

The new layout uses up so much space for each thread entry that only a few are displayed on each page. You now must slog through several pages of thread listings to see them all.
