Well, several months ago, when I was coming back to the Challenge after quite a while away and was a bit "nervous" about writing again, I got on the board here and said I'd like a "buddy," but no one has ever replied. It's not easy to be part of a group when no one wants to partner with you!
I'm okay about it now, but felt "left out" at first.
Also, I read and comment on the "brick throwers" because they are reading and commenting on mine. I do read some others, too, but make the "brickies" my priority. They are taking time for my piece, so I want to reciprocate. I usually congratulate the winners each week, too, and have noticed some entries with few comments, but those are people who have never commented on my work either.
I'm not sure how to vote on this, but tend to think if they really want comments, they'd be brick throwing or making time to read and comment themselves on several articles.
