There's an aspect of all this communications technology that is shared with old-style writing and publishing. It's the question of "is there anybody out there?"
What if I write a blog entry, or a tweet, and no one reads it?
What if I publish a book and no one buys it?
It's a worry. Of course, there is one guarantee; if you never write it, or publish it, then it's certain no one will read it.
That's why it's a mantra for The Write Group that at least one person out there will read your words and will appreciate them.
So, I'm on Twitter. Search for Scribbulations.
