Taking into consideration the current status of both programs - what have you found to monetize better for you? Also - what have you found to give more "value" to site users? Do you feel amazon to be more targeted than kontera?
Would love to hear thoughts and experiences from other users.
I've never used kontera, so might be wrong on this, but my understanding is that it's pay-per-click advertising. OTOH, amazon is an affiliate program that pays a commission when someone buys something. So it's pretty hard to compare the two. My one large content site is very specifically focused, and I need to be able to link to particular products - even to specific products on specific pages - which I can do with amazon (and with the smaller affiliate programs I've used). In fact, scouting out products and finding new items before other sites do is what brings me almost all of my commissions. Contextual ads aren't specific enough.
ETA: I just popped over to the amazon associates site and see that they now have something called "context links" in beta. Is that what you're referring to? It would still have the same difference as stated above - for any payment from amazon, someone has to buy something.
An interesting thought after reading a few of the threads here about kontera and similar in-text advertisers. With amazon, you wouldn't have to worry about the company finding suitable advertisers for your pages (and they have a number of parameters you can set yourself). But I'd still rather link my own.

This is correct. Kontera is similar to Adsense. It took me two years to collect enough clicks, but I finally got up to $100 to get my commission payment from Kontera.
Personally, I find the pop up windows to be rather annoying, so I am removing them from my sites now.
