What's blind about that?

As long as the surfer knows that he is getting a sponsor by clicking a banner or text link, it's not blind. A thumb linked to anything but a full size pic is a blind link. Any type of link that takes the surfer to a desination to other than that which is expected can be considered blind. If the surfer clicks your sponsor link and reaches your tranistion fpa, that's not really blind.

Those fpas are good if your sponsors don't convert well or shut down completely. That way you just swap out the fpas or links to the next sponslor. I personally don't like adding another step in the process though. I always links directly to the sponsor tour.
