Author Web Sites
A few months ago saw a link for a book that looked interesting and stopped by the web site to learn more.
It was a nice web site overall... but I could not, for the life of me, find a purchase link. I even looked for the book on Amazon. Nothing. Not even a 'coming soon'.
I was, to put it mildly, irritated.
So what about you guys? What web site errors drive you batty? (And, to be fair, which web sites do you consider really, really well done?)
