Further to Facebook cease and desist to Robert Scoble's scraping of his own data in Facebook -
1. Facebook doesn't play well with others.
Facebook Open Like A Granite Wall Compiler from Wired.com:
"As we’ve been repeating over an over again, Facebook doesn’t have an API. Flickr has an API, del.icio.us has an API, but Facebook doesn’t and that they would take legal action against code that allows what any self-respecting API is designed to do — import and export data — further demonstrates that Facebook just doesn’t get it."
2. We social members of innumerable social networks need an open social network protocol:
Content access controls - the ability to make some content visible to everyone and at the same time reserve other parts of content only for those visitors I’ve designated as “friends.”
Cross-interaction for existing Social Networks - Why can't I have all my social networks connected? Need: Incorporate your existing data while providing a way to define new friends without resorting to any specific social networking site.
3. Those connections I've made, that profile, those addresses, that content - it has no value unless I own it and can access it anywhere, anytime, across the web. So social networks! Be truly social. Play fair. Be nice. Share. Promote data portability.
