 Launching?
peterlai: My experience consists of one sample point. WebNotes just launched an invite-only beta with decent success. Alex, our marketing guy wrote a great blog entry detailing the entire experience from preparation to payoff. http://blog.webnotes.net/post/2008/12/15/How-to-Launch-a-Sta.... Our biggest breaks came from having mashable and readwriteweb simultaneous write great reviews of our product. From there, we surfed traffic onto the front page of delicious and were picked up by several other personal blogs and websites. Good luck with implementing your launch!
