I agree with you on that, yes. Being on our own can be very exhausting, especially since we're often wondering if we're doing things "right" to make it successful, and if there's a right way to do the things at all. It's always puzzling to see certain webcomics go viral to success, sometimes without even doing anything special for it. There was just that lucky moment when the right person posted on tumblr (or else) at the right moment, and bam! Perfect alchemy. It's like winning the national lottery, you can play all your life and never win –but you'll never win if you never play.
For a mind like me, very disorganized by nature, it's hard to deal with all the social networks things. Clearly, it's not anyone's fault if I'm like this, and I'm already extremely thankful that Tapastic exists at all. I can't describe how blissful I was when I discovered it after paling in such horror at other websites and, worst, domain name registeration things. Without Tapastic, I might never have made more than 5 pages for Singmire Haze. It's just that seeking for more audience outside is a bit tedious to me. More work is always source of a lot of worry orz
At the same time, it's true that some of us have taken initiatives I joined in, like @felipechoque with the Tapactivities, or lately the Secret Santa thread by @l4213 (not to mention the Xmas collab). I think that the reason I felt more like joining those was that there wasn't an overwhelming number of people joining in, so I felt that I could exist in the project, along with the other members. We could all have our identities expressed. I didn't join the Halloween contests because I felt like I'd just get lost in the mass and it made me very insecure.
Thus I think the best way to keep activites successful would be splinter cells in which everybody could win as they'd get to know other members personally. When I see a huge bunch of entries, I don't want to look at them, but if there's just a few, I can take the time to finally watch more of them than if I had been confronted with 100 (or even 30).
And, yes, sorry! I didn't mean bitter about myself actually! I know I'm doing good already, but I tend to be frustrated for others like you who struggle a bit more^^
Maybe an activity that would be good, would be one that would be entirely about presenting someone else's series that you love and would deserve more audience, idk...
