@Carl Hancock - Right. Usually how these things turn out is that a developer purchases a plugin from someone and since they don't have the save vibe as the previous author, users jump ship. So it doesn't always work out as well as it did here.

I think $39 for one year of GravityForms is a steal and I have no problems with that price but then again, my tolerance level probably peaks around the 50-60 dollar price range which is still affordable but not out of my price range.

I wonder if GravityForms is still showing a major upward swing in growth or if it's slowed down a bit and is now a gradual climb. Which license segment has the most customers, the Developer tier or single site use?

@chris mccoy - It was listed in the post which plugins he sold.
