Quote - I'm just wondering how much longer sites like this will be around.

How long will 3D sites be around? As long as there are people using 3D products, I suppose. To me, selling 3D on Facebook is like selling any very specialized item at a 5,000-acre general flea market with everything under the sun for sale. The odds of someone needing your specalized item walking up to your table are much smaller than if you're selling at a 3D-specific venue.

But good luck in your venture. Just be ready for spams & scams.
