So as a creator, I can understand the disappointment when people don't comment on your stuff. But as a reader, I can also understand some reasons why people don't comment. Sometimes there's just nothing to say and you don't want to annoy the creator with repetitious or insignificant comments. Sometimes just 'liking' the page works best.
But then there's more specific reasons: for me, one of the main reasons I don't comment sometimes is because I forget the character names. Seriously, if the names aren't in the description or someone hasn't used them in the comments, it can take me a long time to scroll back up and try to find it used in the comic. And yeah, I have to use the character names when commenting about them, because it's just embarrassing to keep saying 'that dude' or 'that chick' and wonder if the author's disappointed you don't remember their character's name.
And the other most common reason for me is just not having the energy. I fluctuate between commenting on everything I read to just 'liking' everything because I'm tired/depressed and I want to show creators that I still care about their work.
Sooo what are some reasons you guys don't leave comments sometimes? Or, alternatively, what are some of the comments you leave the most (i.e. puns and jokes, comments on the art, comments on the characters, etc.)
