Blog spam has gotten smarter. It looks just like real comments and it is often undetectable by anti-spam plugins. So how can you beat it?

A while back, we created a list of the most annoying website features. We thought that our list was pretty complete, but apparently it wasn’t. Lately, several other bloggers have also chimed in with a few things that they’d change to make the web a less irritating place to be.
