I'm sure this has already be said, but most hacks here are not big enough to be considered a commerical hack. That all depends on the demand of support and code really. If you have a huge hack that 1000's of users will use, then you could consider having a commerical site for that hack because the demand in support is to much for a simple thread to handle.
I've always seen alot of users going commerical to make a few quick bucks, but really if you ever want to go commerical with your hack. You should ask yourself a few questions....
1. Will 1000's of users use this hack?
2. How far can I really extend this hack?
3. Will the support for this hack really be to overwhelming for a thread to handle
4. Does my hack really have enough code to be marked as a commerical product
This is mainly why I've never opened a commerical site for my hacks. I havn't really created anything I would really consider to be a commerical product. I simply enjoy coding, it's fun and a great learning experiance.
I could understand why one would open such a site because of the demand of individual support that is required. TheGeek is a perfect example, he doesn't charge users for the code and the features the product comes with. He charges a
small fee for greate individual support.
Anyway, thats just my $0.02.
