RSS, semantic markup, microformats, and open APIs all enable interoperability, but the big players don’t want that — they want to lock you in, shut out competitors, and make a service so proprietary that even if you could get your data out, it would be either useless (no alternatives to import into) or cripplingly lonely (empty social networks).
