I understand its utility when opening links in the same page but if you're already opening all threads in different tabs, I don't see how you ever even notice that underline. Unless you're obly opening one thread at a time? If that's the case, wouldn't it be easier to just open in the same tab and let the read/undead indicator do its job instead?

Either way, that manually set CSS hover wouldn't do anything for you as you won't be hovering over the link when you return to the page. Like I said, this is a browser feature, and an inconsistent one at that.
