It happens, but not too often. Guess I ought to check that out. I've not checked my tracker in ages. For a while I got to where I never shared a link of mine, yours, or anyone else's unless I used the tracker. . . . .but now I'm more convinced that my time is better spent worrying about other things.
One of the more important things that is overlooked, in my amateur opinion, is developing authority within a niche. I've got a dozen niche's going, and I should be concentrating on just a few niche topics, and not so many - I've effectively prevented myself from developing Google and reader "authority" within some niches by writing in so many different ones.
