I always find it odd when a well-known public figure, such as a film star, author, or celebrity, goes out of their way to "announce" which political figure or side they are casting their vote for. Voting is usually set up in a way that gives the voter complete privacy, so their decision is theirs alone. It's weird that some people have to go and make a big fuss about it. Why not just say why one should or shouldn't vote for certain sides and not make some big announcement?
What's even worse is when the person picks a side they know they will get hate for, and also don't agree with as much as some of the other options, and then go on to try to justify their choice.
I'm currently torn with how I use Instagram. Of all social platforms I'm on, I have the most friends who see what I have to share, so if I have a life update, it's the place to share it. On the other side, the fact it's owned by, and becoming more and more integrated with, Facebook is worrying.
