I usually try to keep up with everything the big names release and use

to do so.
I have read countless books on copy writing,
seo, affiliate marketing, and any general making money online methods black or white. Knowledge is power in my opinion. There is always going to be crap floating around but I find I can pick something up out of a lot of the big name stuff nearly every time, they are always innovating and thinking outside the box in affiliate marketing.
I just watched the Dominating clickbank 2 vids and I can say although nothing was groundbreaking I learned some new things and overall they were very solid videos. Worth the price imo although there are definitely sharing forums that are dead against paying for anything mentioning the word ebooks.
I know for a fact an individual on this forum who has gone from 1k/month - $10k/month just from reading one ebook and applying the methods in it. To say all ebooks are useless is an over-generalization and ignorant, although if you go blindly looking for IM ebooks online without knowing who the authors are I'm sure it's easy to get that impression.
edit: I do half expect the OP or shill to drop a link or crazy new ebook in a few posts down...
