For those who are interested in maximizing their Twitter experience, there is a two-day Twitter seminar in Los Angeles on September 22-23. Dubbed 140: The Twitter Conference, the gathering will bring together nearly 50 speakers and panelists. From social media experts like Biz Stone (Twitter co-founder), Guy Kawasaki (Alltop co-founder), and Noah Everett (Twitpic founder) to an odd hodge-podge of celebrities, the conference has a track for ordinary folks and one for developers.
At this point, the early bird discounts have expired and the registration fee is pretty steep at $429. However, if you want to mix and mingle with some of the industry's movers and shakers, this is an excellent opportunity. You can also view the attendee roster so you can see who you might want to network with while you're there.
If you go, have fun and soak it all in. There is also an open bar the first night which might help you feel better about the high registration price (although I doubt anyone can drink enough to break even on the $429 fee!).
