Most of the time I just and run because I am not very good at expressing myself through words and can't seem to find the words that I want. I feel bad about not commenting but I also wind up getting frustrated with myself because I am unable to say what I want to. I do look at the work and I only if I really like it, I find it meaningful to me, or it touches me in some way. I do try to comment though and sometime I am able to and withs it was more often but I also don't like to just keep saying things like "cool".
I mind when people mind if they get a without a comment.
Sometimes people like a piece but don't have time to write a comment; and sometimes people like it but have nothing relevant to add. I'd rather have a and run situation than just some random and generic comment.
I try not to fav and run, but, at times, there just is no time, so, I'm guilty of it, too. But, I'd prefer a comment, if for nothing more than to find out what the person liked or didn't like about the photo, so, I could continue to learn and improve.
