I would sum that up as simply be yourself and let it flow.

Perfect. Couldn't have said it any better.

the sad part is that quite often great posts don't get too much engagement due to a lack of visibility, and I would make a sort of a side trading page where there should be featured the most engaging posts

True. Content discovery is an issue. Hence the use of tags - the right community - and even timing plays a vital role from my experience.

I really like the idea of engaging posts (like HOT posts in the sidebar).

Thanks for stopping by! :)
