Digital Citizenship Internet Safety

I went into my Twitter settings and turned off phototagging. That means that only people I'm following can TAG me. My tweets are only visible to the people that follow me. I probably wouldn't even have a Twitter account, but I had to set one up for another class that I took last fall. I don't like the fact that advertising is part of Twitter...I need to figure out a way to control that as well. I guess it has it's place, but I'm not a big fan of Twitter.
