I guess it really comes down to what you are comfortable with. I don't tend to post a lot (either on this board or others) as I do not usually have much to add to many of the discussions that are taking place on the board(s). In the case of this board there is the exception... the photos section. When people finally get past their anxiety about posting a pic (as I am sure that many have) I think that it is reassuring to the poster if there is good positive feedback... even if the comments might be repetitive in nature.
