I'd like to add another dimension to this. I have a new blog that next to nobody reads. But...

I mentioned Realms of Fantasy in passing, wondering if they were publishing yet ... then went on to talk about my discovery of the Writer's Digest yearbook on novel writing which may become my text for writing my next WIP. Just a little phrase. No keyword.

The next day, the publisher made a comment that they were indeed publishing.

The lesson I learned fast: you never know who might end up reading what you say in a blog -- even if you think you are anonymous.
