I'm not happy about the CA stuff.
I suppose it will be that way for all of them, eventually. What I don't like is the randomness. I wish VISA would just lay it out for
all of them so we could get on with it. I haven't been doing much of it lately. I guess I'll wait a bit before I decide if it's really a disaster. Depending on your niche, AVS can be really good and productive traffic.
But I'd still say CA, CSN, UGAS. There's big changes coming for all of them. Pick a stable one with good payment processing options.
