Ah,, everyone has their own reasons...seems the "ratings" has the lowest value at all. If totally confident in an image I frankly could go with no comments at all. Still, I like to comment once in a while and leave that option open on my gallery postings. Once in a while, just a rare once in a while, I do get a helpful comment. Most of the rest simply make me feel better about the shot or are interesting at best. I do like comments for the simple reaon it provides opportunity to meet others with similar interests..artists and wanna be artists and will-be artists I did not know were here. Then again, if confident enough with an image as I have been with a few, no comments seems just fine. I suppose lots has to do with what fuels our drive or helps us keep moving.
