Hi Stevie,
You are right. Tons of places to meet people, even if just for friendship.
I've met people on Twitter, Facebook, Google+, Foursquare, Pinterest and Instagram. I have met tons of new people on Instagram.
By the way, if you are on Instagram please follow us at Hairboutique. We follow back and look at all the photos of our followers and leave comments.
All you need to use Instagram is an iPhone or an Android phone.
