Good read! This came just in time for me. I've been getting a bit discouraged with my level of success on Tapastic plateauing. It seems like Tapastic works best for the people who are already successful - namely, the people with the most views, likes, etc. It's hard getting over that hump.
Just like Tapastic, your success on all of the social media platforms rests on how active you are in the community. So managing a decent level of engagement Instagram, Tumblr, Twitter, etc. feels like a full time job - and THEN you have to make time to actually produce the content. Would you suggest going all-in on just one site, or taking advantage of the exposure to different audiences on all of the platforms?
