NaBloPoMo 7 What percentage of yourself do you think you reveal to people online?

Hmmm this is a tough one as I honestly think you will never know someone 100% by just reading their blog but I think you can really get to know someone from other social media like their personal Facebook. Of course it depends on how open you wish to be.
I think people who don't know me that well are often surprised by my crazy photo collection on Facebook as I think I come across quite shy and quiet. However my FB photos tell a different story (particularly uni ones), of course that was a few years ago so I'm sure there won't be as many crazy photos now.
I think I'm open and honest so I think 90% of me is revealed, I doubt you'll see my full angry self, although I do like a rant!

Me back in the uni days.

A bit more sophisticated these days ;)

Do you think you reveal 100%?
