The chat boxes that
actually are chat don't bother me. Provided they don't try to pop-up unrequested or otherwise make themselves annoying, I actually like them. They can be really handy for asking a quick pre-sale question or getting support.
The ones that are just a shitty interface to a FAQ suck, though. I don't even like it when they're as you describe, because its eventually turning into an actual chat with a real person is kinda-hidden functionality.
