David, how large is your Watchlist? Most of the time, if you monitor your activity feed, the profiles don't really need anything more, although it is nice if you improve them as time permits. I agree with you; I don't like to let go of profiles when I have an interest in them, but for the most part, they wait patiently for my attention.
Now that I look, though, you may have a huge Watchlist due to a gedcom upload?
