I just realized that this week's blog-"Interesting Findings" (See below) completely negates my earlier rant on social networks and joining reader groups to "friend" someone for publicity's sake.
Now to be fair, I have only "friended" people I know or am in a group with-so no massive "friending" going on. And I do not send out "read my latest book" bulletins, and other advertisements as some authors do. But- I have to admit the advice was right. (Yes,shudder I've gone over to the dark side.) Social networks-used responsibly-do work as a way to draw readers to your website and ultimately your books.
