You nailed it, M.. I too find the sudden influx of new users asking somewhat "off" questions to be odd and off-putting. Having new folks come on MP is great, but the sudden rash of questions so recently since the "mobile-device-friendly" change does indeed make me, like you, wonder if there's "generated content" happening.
Though the colossally dumb "Could I be pregnant?" questions have been around, off and on, for a long time....
I hope the moderators are heeding these posts like yours and Diane B.'s about the huge issue with her real name appearing on FB due to an MP post. Again, new users with fresh questions -- that's great. But between the gray, glitchy, ad-ridden screens I see on my non-mobile device, and these content issues, well, I'll still come on to see what some folks are posting and answering, but I won't do it as often.
