Hmm its tough to say. Problem with time here is that possibly a lot of those followers that you amassed over the year no longer use the site?
The best way to build a following is naturally interacting with people that have similar interests as you. I spend more time interacting with other's posts on here and building new friends than I do on my own post. I don't necessarily do it with the intention of "earning" from their friendship, it all comes naturally.
I can see that being true although i do get out there and talk to a lot of the photographers i just wish that i could be earning half as much that would be awesome. not that i can really complain it is free money after all lol. i just gotta figure the secret out and i think i will get up there soon.... i hope!
