I hear you, and I feel your "pain."
For some 20-odd years, I have been part of a vast array of social content sites — some that compensated contributors, some that didn't — and the bottom line is that I am inevitably disappointed.
Social content and social media isn't — are rarely was — about quality. That said, it's also not necessarily a popularity contest.
In order to keep my frustration at bay, I instead ask the question of whether or not something adds a measure of value, in-context. Most Actific posts, and now DrugWars battle posts don't add shit, so I don't tend to curate/upvote them. A cute original picture of someone's cat? Maybe it does add some value, within the context of what we're doing here.
Sure, I have friends here... but I still don't go around and mindlessly upvote every piece of content they put out there.
I originally came here because I enjoy a genre I call "social blogging." I'm still here for that, and it's still what I write... and it's still what I tend to follow and curate.
And yes, I often spend two hours on a post. In 2+ years, I think I managed to post four posts in one day twice. Mostly it's once daily, sometimes twice.
