I do see what you are talking about on a few random threads, but I think that it's life. We all have bad seasons in our lives, and I can understand getting support or venting on the board. :-)
I'm in the weight loss challenge and the ladies have been so supportive to me, and informational as well that I have lost some weight. So, there is a lot of good to be found here. I tend to skip the really negative threads if I'm not in a place to be helpful or supportive.
For a positive aside, the lady who works at my local walmart fabric area is always friendly and helpful. My husband just spent time helping me pick out some fat quarters even though I take forever. :-)
