Interesting, but I am not even looking for a community, I just don't want to put a post out there that will be "unsuccessful". It doesn't bother me if I only get a few likes, it bothers me that all my friends see how my post is "failing". I am not in panic but it puts me off from posting. Am I the only one with those thoughts? Facebook without the like mechanism would cater to me much more.
Whatever posts I make on Facebook are usually things I genuinely want to share, whether it's photos while I'm traveling, or link to an article that I find really meaningful. Some people will see it, they might even like it but not press Like, I don't really care. It's something that I wanted to share and I know it reached someone, and that's all I wanted to do. It could be an article that explains really well what Net Neutrality means and why people should care, or it could be an amazing waterfall in Iceland.
Incidentally, I subscribe to certain subreddits about hobby topics (like Dragon Ball Z), and whenever I make posts on them, I (irrationally) care more about how many upvotes (or worse, downvotes) my posts get than I care about my posts' "success" on Facebook. So maybe I do know what you mean, but I see Facebook differently (and more personally and less social-media-y) than everyone else does.
