Important post, Mateja. A well crafted piece is worth taking time over. And finding a great image to pair with text can be a real time suck though worth it. And even all that is no guarantee of higher stats. Something to aim for though.
On the other hand I wrote a response to a post yesterday that was recommended and commented on by two people (one being the author of the original post). And that gave me a 100% rating!
Which makes me wonder how significant are stats anyway.
