My Twitter account is the official account for my website A Girl and Her Kindle. I share book reviews, information on indie authors, links to free Kindle books, etc. If you need to spread the word about something Kindle related, let me Tweet it for you to my 1800+ followers.
Limitations - What the user will and will not tweet about.
Anything Kindle related that's NOT pornographic. Erotica is okay, but remember that A Girl and Her Kindle is geared towards women.
