Challenges of the startup entrepreneur and where is social software going

I am about to share some thoughts at Sun Microsystems about entrepreneurship and social software. I am just going to share the bullet points here and try to enhance it as a real blog post. I have been asked to share about the challenges of a startup entrepreneur and my views on some social software trends. Let me know if I miss anything?

Challenges of an entrepreneur

-find a space (not an idea) and execute as fast as possible
-differentiate and innovate, no copycat
-launch fast in alpha and iterate, do not wait for a perfect product
-gather an initial community and get its constant feedback to improve the product based on the feedback
-find funding fast and try not to lose too much time on it
-gather a kick ass team (top challenge: engineers, especially in the bay area...)
-scale, open as fast as possible the service
-communicate constantly with the community
-keep momentum going after initial launch
-stay on your main market or localize fast?
-manage an international team (Seesmic is already on 3 continents...)
-create a great API and gather a developer community
-integrate in major social software (see my social map post)
-reach critical mass
-find the business model and grow revenues

Social software trends

-content versus conversation
-decentralized instead of centralized on blogs in the past
-immediate versus lots of thoughts (microblogging versus long posts)
-"disposable"
-open (API, open source)
-open customer service (see getsatisfaction)
-sharing as much as possible with the community to enhance the service
-more human (a face on the Internet users, Seesmic helps this in video)
-live versus asynchroneous
-the web in the pocket (iphone, Nokia n95) changes the deal
-ecommerce and recommendations through the filter of your friends instead of marketing
-news finds you through your friends instead of getting it from reading mainstream media home pages
