Well, when someone asks me - the main perk that I have found are the friends I have found through blogging.
My absolute best friend, who knows me inside and out, she knows what I think about everything, and often what I think about the people around me I met on my blog. Her name is Lara. We started our blogs about the same time and we were both posting on 2P's in a bucket and we'd see each other's links in our posts on 2P's and click over. Our first like 3 or 4 posts were almost the same.
It was eerie...
And then I realized I knew her husband, and Drew knew her. And basically we had traveled in the same circles our whole lives without really ever crossing paths.
Sad news, I don't think I actually have a picture of the famous Lara... This is just her profile photo. That's sad.
Anyway, sometimes it's just hard to find people around you who really think like you do. Blogs allow you to find your niche. To find those people who DO think like you do. I LOVE that part of it, I adore it. For that alone I would keep blogging.
Have you found friends via blogging? Am I your friend? I hope so. A person can never have too many friends. :) Well, maybe -- but I'm not even close to my quota. :)
