All the bad parts of AOL, that is.
Facebook wants to be its own self-contained information superhighway, something you never have to leave. It encourages companies to abandon their own web sites and replace them with Facebook pages for people to "like". it encourages people to replace email with writing on walls and sending Facebook messages. It encourages people to post video which can only be viewed on Facebook (despite apparently being hosted on YouTube, they cannot be found by going to YouTube.com--how did Google let that happen?)

Back in the AOL days, AOL did similarly with AOL "keywords". Around that era, email was the method of "social networking". There was a time when if you were on AOL, you could only email other AOLers. CompuServe folk could only email other CompuServers, The Source could only have access to The Source users, Prodigies only talked to other Prodigies, and none of their email addresses had an @ in them. Eventually they all got email gateways to the RFC 822 and following Simple Mail Transfer Protocol (SMTP) standards, Hyper Text Transfer Protocol (HTTP) came in RFC 2068 and following, and all those little isolated city-states pretty much became ghost towns.

Who's writing the SSNP (Simple Social Networking Protocol) RFC?
