Goodreads Authors/Readers discussion

I interviewed an author who really nailed his book launch to know what his "best practices were". Three main things came across:
- you need to have a street team that you build while writing the book
- you need to reach out to as many "influencers" as you can before launch and try to turn them into early evangelists
- you need to leverage existing platforms (blogs, high-traffic websites, etc.) to get the word out
- all that works much better if the book is free at launch (then paid after a few days)

What other tips would you add?
(Here's the link to the interview I mentioned, well worth a read)

Personal appearances at public libraries, book stores, literary festivals and conventions, and book clubs. Demonstrate your appreciation and respect for the attendees by delivering a professionally prepared, well-rehearsed presentation with book-signing pen in hand.

Express your appreciation for the time and effort expended by a publicist or marketing agent on your behalf by promptly following up on all leads provided by them and providing them with updates regarding progress or lack thereof.

Very nice, I'm sharing this. Thanks for posting!
