Oh, you got popular whenever the fandom was becoming popular. Yea, nowadays I see lots of people jumping on the pony band wagon. The sad thing for them is, unless you started out early, I would say around 2010, 2011ish, there is no way to be popular anymore. The superstars of the fandom, especially the ones who came up with the 3D renditions, are well established and I don't see any more popping up. I myself just do it as a way to learn Inkscape because lets face it, ponies are not that hard to vector.
