When I was still active on DeviantArt regularly, but before I got Gallery Director status (2004-2008 ish) I sold little prints, but consistently. After GD, I overall sold about double, but the interaction was like an EKG, and full of noise and stupid complaints and random stats-whoring from commenters. It felt like too much of a rollercoaster managing whatever turdstorm may or may not arise.
I'm still trying to bootstrap a regular pace with PF, as I'm still a very active IG user, but I may just test out if the Import function can handle JSON file with over 10K posts...
