The IPO was overvalued in my opinion, but I don't think the stock price is a great indicator of the future of the company. That said, I think a decline is possible, but will it happen soon? I don't know. Maybe the backlash will come from kids whose parents are essentially building profiles for them.
I couldn't decide if this would be awkward or not before I jumped in. After using it: kind of awkward, but totally fun and enlightening. I was impressed with every person I connected with.
One person called me boring, though. (I am boring)
