Great tips and something I should really pay more attention to. I've been out of the blogging game for a few years now and lost all the templates, markdown and pretty little images I used as dividers etc - now I can't even remember how to center text in a post!
Since coming back my posts haven't attracted much attention but it's early days still and it seems like you have to work harder than ever for readers, but then 3 years ago I was "in" the crowd, now stood by the wall watching the young kids have fun dancing and trying to not look too weird! lol
OH please don't center all the text in your post :)
It does take some time to build and then rebuild. It's not so much the way your post is presented as much as writing well, visiting others and engaging. IT does indeed take time.
