I periodically see that people I don't know have visited my page...and have never thought anything of it. I assume that they're newer members, or perhaps people who are still reading and not posting yet....and that something I have posted has resonated with them somehow.
Or....maybe it's an accidental click...I've done that myself more than once and suddenly found myself on someone's page.
I recently deleted my Facebook pages...both work and personal. It wasn't to do with anyone here...just felt like I wanted to be done with the kinds of input I was getting there...
