Ouch. I tend not to use a signature on Amazon too often if I'm posting about something unrelated to my writing, because I figure it irritates readers if you post a siggy too much. But this thread I started was mentioned and linked to in an article about Amazon's new bestseller list on Daily Finance, an AOL money and finance blog. There's my name at the very top, being glanced at by God only knows how many readers... and I didn't put a siggy with a link to my book. Tsk. There's a missed opportunity for you!
