Everyone has different motivations to share their work. Some do it for fun, some to learn themselves, some to market their experience, some just to get pat on the back for good work and from need to belong to community. If you get sustained living from writing add-ons just for sake of sharing them here for free, good for you, but as I have seen people who share their add-ons write them for their own purposes and just share the work with little of extra work. It's totally different from doing the work solely for the purpose of sharing it here, but you could show us a good example and do as you preach and write the doc, right?

Anyway, personally I would be surprised if vbulletin.org running ad-free and adding plenty of extra value to the product wouldn't get any cut from vB sales or otherwise benefit financially from the product, or that Lynne for example who's providing plenty of support for the product would be just donating her time for free and helping people here with just pure sweat equity. It doesn't make business sense to me, but like I said, I guess I'm too much of a capitalist and actually have to get paid for my time to pay my rent
