I submit 3-5 galleries a day.
Tranza, Fuzebox: there's still money in submitting ;) You just have to do it properly. Maybe a year later I will say there's no money in submitting because my other projects will make me more sales with less work, but today I am 100% satisfied with my results.
There's no money in submitting if you're doing it this way:
Put sponsor banner on top, under that 3-6 videos offered by sponsor/copied from FHG or free pic content with premade lq thumbs boosted by 1-2-3 "take the tour" or "join now" or similar sponsor links and submit it with any autosubmitter. You just waste your time if you're using the same template more than 3-5 times or if you're pushing the same sponsor or same site every day, etc...
I promote ~20-30 sponsors, 100-150 sites. It works, believe me ;)
I had to learn photoshop and some html, but these are useful skills which I can use out of adult as well.
