Let me play! Let me play!
Couple of points:
1)I definitely think content has a big impact on gallery performance and therefore it needs to be either the same or from the same set or artist or whatever. Similar enough that everyone agrees that that is not a factor in performance.
2)How will you track which gallery converted to what?
3)If Shemp is supplying traffic, but doesn't do anything other than URL then there has to be a trusted arbiter that is not playing to run the back office on everything.
just my 3 cents.
