And really, that's kind of nasty of Google. I could see that if they have to mail a check, but if you have given them your bank information for electronic transfer, they really don't need to set it that high.
Imagine the money they earn on all that money, some of which will never be paid out.
Of course YPN did the same thing. Many of us dropped them as they started to slide and of course we had to leave small amounts of unclaimed money when we did. I just got my final little deposit from them recently.
I forget what Chitika's minimum is, but I know it is under $100 because it's almost always less for me, but they still put it in my PayPal every month.
No reason Google couldn't be more reasonable.
