Every day someone shows me a Kindle and asks jokingly if I can sign Startup Communities for them. This is one moment when I wish I always carried a sharpie or a paperclip with me. I adore Kindles too much to actually ruin them, but the thought crosses my mind every time I hear the question.

There is however a way for me to sign Kindle versions of my books. It’s a super cool app called Kindlegraph. Simply go to it, authenticate with Twitter, and search for “Brad Feld” or “Startup Communities” (or just click on the preceding links.)

As an author, there’s something emotionally satisfying about signing a book you’ve written. I guess it creates another connection with the reader, which is bidirectionally powerful. I’m glad I can now do it on the Kindle as well as on physical books.

I’ve always loved getting books signed by the author. As an author of two books, it makes me smile a huge smile when someone asks me to sign a copy of my book for them.

With Kindlegraph, I can finally sign my Kindle books. I met the founder, Evan Jacobs, at Glue a few months ago. He had just started putting books up on it and I immediately told him that I was game to put Do More Faster up. I tweeted about it and signed a few.

Now that Venture Deals is out I’ve got them both up on Kindlegraph. If you have a Kindle version of either book, or you are buying one, and want me to sign it, just go to my Kindlegraph author page and request for me to sign the book.

And if you haven’t bought the Kindle versions of Do More Faster or Venture Deals, what are you waiting for?
