It's tempting to reply to this with a "well, fuck off then." but it's valid critique - some people don't want a presentation, they just want text. Look at man pages - it's possible to improve the typography and the presentation, and include some graphics and CSS, but the information is what people want.

As a contrast, look at the mostly positive comments on the 180 days of whatever it was posts - some of the more negative posts got downvotes, and most of the comments seemed positive.
So, maybe it's useful to (avoiding age[1]) say "I'm learning $X and this is what I made? Any useful critique?" You'll still get arseholes but I think you'll have not as many.
