I have never even looked as to who has viewed me. That is an indication of just how much I care.

A lot of them are "hovering." I do it accidentally all the time, particularly in the Memes R Us group, where everyone's picture is right there by the thumbnails of the memes. It happens a lot when you're using a mouse. I ignore the ones that say "hovered."

I usualky read profiles when reading a comment to get perspective. Also if those are people that hovered it may have been accidental.

I don't really care, personally. People look at things for a variety of reasons.
