Come On! Generally speaking, ethical and cool have nothing! to do with this business. And I'm pretty sure no one here thinks acai berry is ethical or cool for that matter. What's cool is making money.
Clickbank is a good way to make money(If your a vendor), and a good one for beginners to learn marketing.
Overall the reason why clickbank is laughed at so much, is seen mostly as a newbie network. And the second reason is because it's so easy to start your own product on clickbank, which makes almost 99% of the offers junk. I started promoting with clickbank, and did some good numbers, but after that I just signed up for a vendor account, and started promoting my own product. Don't get me wrong, if i found a clickbank product that made money I would without a doubt try it.
Bottomline: Conversions is King, and most(95%) clickbank products can't hang with CPA conversion wise. Don't get my wrong, straightsale is slowly coming back, and clickbank can come back stronger than ever. I like straightsales, i feel better selling it, its just may end up being the new CPA oneday

As long as Google/Facebook and others keep cracking down on the scammy stuff, there's going to always be a life for Straightsales and Clickbank.
P.S. Finally It's way easier to make a clickbank vendor account, yes, so there's going to be a lot more junk on clickbank. But you could also argue(not really) there's more niche markets aswell.
Yeah this is basically a CPA thread, not because everyone here likes CPA more here, it's because it's whats making money at this time, and that my friend, is cool.
