Although today's post should be our Part II about applications, I'm going to take a bit of a break to talk instead about some settings. I know we're all concerned about (and should be) the settings that we have in these various social platforms, and one came to the forefront today - which I'll get to in a minute.

First, I want to make a comment about privacy - the short version is that nothing on the internet is private. That's right, I said it - nothing. Whatever you write, post, tweet, tag, etc. lives somewhere online forever. Even if you have the strictest of privacy settings, what you say can become public. So just bear that in mind whenever you're using social media - if it's not something you'd say to your grandmother or show to your grandmother, you probably shouldn't post it.
