Since you asked, here's a real nit-pick:

The links for "next newest topic" and "next oldest topic" work backwards.

The "next newest topic" link goes to a newer topic than the one you're at. However, think about people lined up by height. One is the tallest. Then comes the next tallest, who is shorter than the one you're pointing at, and so on down. The "next tallest" person to anyone is shorter, that is less tall, than that person.

So, "next newest" is the one that's next in line away from being the newest, that is, the one posted to before the one you're at - i.e., it's a bit older (or less new). But the link takes you to one that's more new (newer).

Same for "next oldest;" reverse everything.

You can fix this by changing the words "newest" and "oldest" to "newer" and "older," respectively.

(I said it was a nit-pick! )
