Please dont be too surprised. Share what? The text of my ads? How much I spend? How much I earn? What words I bid on? What niches convert best?
Why dont I just punch myself in the nuts after I flush my money down the toilet.
I'm just trying to make the point that you are potential competition and people are naturally tight lipped, thats all.
Again, not trying to be a jerk (I swear!), but pointing out why you wont get much specifics in such a competitive area.
Having said all that, I would point out that PimpRoll has lots of linking options that other bidders might not be using yet. Give us a shot if you need lots of niches and linking options.
