I would agree with the OP, except that two areas wouldn't go anywhere that I can think of.
The Dirty Talk and Links sections are the ones that I mean.
One point I would like to make for the current set up is that you can browse other sections that you wouldn't normally all from one page.
Like for example, I have never entered the regular Love Hina section because I have never read the series, but I read a lemon written by Alpha Zulu in the Love Hina lemon section, basically because he wrote it.
