I'm not disagreeing with either of you at all. But all the sites in my OP (except MyFreeCams) are traffic sites -- not subscription sites.
For example, iFriends.net comes back at only
$692 daily and
$1.1Million total value. But that is ridiculously low. iFriends isn't what it once was, but those numbers are insanely off.

SO... WorthOfWeb's algorithm/estimation has to be based almost solely on traffic values -- not subscription values.
