I'm not a FB or other social media person (by choice; it's not that social media and techy things scare me) so I don't really get the "Like" thing. I come on the board and see (courtesy of the Alerts tab) that 21 people have "liked" my various posts. That's all well and good, but do people really like EVERYTHING I post? I cannot believe that is true. What is the purpose of "liking" something?
