It is definitely going to be interesting.
It seems to me that it won't take too much to have a pretty big impact. Honestly though, I'm not so sure I want this to be Grandma's next Facebook.
I hope it is the platform that is all about quality. That is where I believe the greatest value will be realized. We need constant vigilance (curation) and a culture that enhances that. When that happens, we will be in a very interesting place with an abundance of value.
Well, this site is being developed as we speak and changes will be on the way! With great changes comes great power and with great power comes greater rewards ;)
