I've been on here since it began as Mamasource. It's not b/c of the summer, this board used to be busy year round and even more so in the summer.
But I've noticed the same thing too. I've also noticed the type of questions that aren't being asked. The questions with sincere need for help have decreased. Mamapedia has changed over the years. It has evolved, as all things do in life. It used to have few tight knit groups of women that followed each other, along with so many that were consistent contributors. It was obvious many of the women had formed friendships outside of Mamapedia. Of course as time went by, more women have joined and the intimacy was somewhat lost. Then men started joining the group, which I have no issue with, but some women did not want to share intimate secrets with men on the board (I have to admit, I had a question I wanted to ask once, but it was too private and I did not want a man's opinion or a even man reading it). As well, the trolls multiplied and has now become weekend entertainment. The Facebook issue contributes to it too.
The board was very open and honest at one point, women were really helping each other. However, for one reason or another, many responses have become snarky lately, as well, some questions have too. Because of all of that, I feel more superficial questions are being asked b/c of the fear of being attacked. I have seen some very genuine questions asked and they had received 1 or 2 viscous responses, not negative, viscous. Even if it is only 1 or 2 mean responses, many just don't want to open themselves up to that.
I enjoy the site but I visit it less and less due to many of the reasons I stated above.
