I like them... they do convert, and they do pay.
Recently, they seem to have gotten on the "spam affiliates with ebooks" offers which annoys me. ... I mean... everybody's doing it all of a sudden, from WWB to software subscription companies.
Okay ... going OT ... but some marketers that were respected like Perry Marshall and that QuitYourDayJob guy (not the dayjobkiller guy) are spamming other people's ebooks. Annnnnoooooyyyying.
But otherwise, I like them.
