I think the point was a low participation system relative to the web as a whole has meant systems where many bloggers accumulatad less than a withdraw transaction fee each. Aside from that, they need all the bother of registration.
I'm not really sure how I feel about the idea that everyone should be accumulating money on all these things. It kind of devalues things to have people trying to make a lot from micropayments mixed with a more hobby web. I think I've eventually turned away from everything that had some get rich quick schemers show up.
