You have certainly been giving a fair bit of thought in the comments that you have written so far. I do think the value of a post isn't so much in what you learn from it (information-wise) but how much it made you think, and whether it compelled you to take some action. So even if you watched a 'bad' movie, if it made you think critically about why you thought it was bad, and inspired you to make a 'better' movie. The point you are making about the comments is quite valid in many ways, and it certainly contributes to the post in more ways than one as well.

Fast food has the effect of making you consume quickly, at a larger volume/quantity than you should, and discouraging you from cooking yourself. I hope your early experience of Steemit is more like wandering through the alleyways of an exotic country and finding interesting cuisines rather than a foodcourt full of takeaway food.
