Actually I've been thinking about this. Maybe this is a strategy based on research.

Maybe these programs know from experience that surfers buying memberships don't rebill all that well for their plug-in filled member's areas, so they have weighed the costs of producing more exclusive content versus just capturing the initial membershp and they calculated that it's not worth it -- or the costs are too high.

Does that make sense?

Let's say I have site and I have produced 20 movie clips and made my members area. If I invest another $3000 in content every month, am i getting that money back in another $3000 in new memberships or is my return the same if I do nothing because new traffic keeps buying?

Cheers,
Michael
