Do you click through on "relevant" links?

Or indeed, any link that does not describe what is at the end of the link?

I am put off by “relevant” links. I never click on them. Well, I won’t any more. I clicked on several that turned out to be irrelevant. I think it’s rude to put a “relevant” link without explaining why you think it is relevant.

Do you click those links? Why? How often are you glad you clicked through?
