I am still writing quite a bit. Because it's much easier these days to write on my phone, that's what I do. And most of my words end up on Facebook.
Which is fine, for people on Facebook. But apparently there are tons of people out there who do not use Facebook for various reasons. For them, going on Facebook is a pain, so they avoid it.
Which means I need to put my words elsewhere to get to the non-Facebook people. But would the Facebook people be less inclined to read my words if I don't post on Facebook, and just link to my stuff elsewhere? I don't know.
Does it matter to me? Yes it does. I like people to read my public words.
