If the Kontera clicks pay lower than Adsense, then don't you worry that people are clicking on them who might otherwise click on Adsense ads, causing you to lose money?
That is a good question.. however I use vibrantmedia, they pretty much do the same thing...
I have not noticed much of a drop in my CTR at all to my adsense... and yes VM does pay a lot less the adsense as well..

I can't comment on Kontera - but when I researched I saw a lot of sites that with Kontera they were showing backfill results from Y! (I think) - which means low CPC rev rates as you are getting a % of a % plus, and even with Y! they simply don't have the level of advertisers to fufil a lot of smaller keyword terms.
