What I had in mind was more general than that - keeping in mind that
the main way I want to use this is to narrow the amount of information
I feel compelled to read by subjecting it to a form of peer review.
Maybe then "approve" is a bad term - maybe "recognition"?
Let's say there was a post which contained points you agreed with and
some you disagreed with. If you care about the topic, and wish to
address the points you like and those you didn't, making a followup
post is the best way to communicate that. But, you would still put
a mark of "recognition" on it, so that when I come through the archives
looking for things you and others thought merited attention, then I
see this post, and your reply. If it's a subject you have no interest
in, you don't mark it. If it's another piece of spamming by the law
firm of Canter and Seigal (I can never spell their names right) then
I could even give it a negative recognition, if we found such
appellations useful.
