Jennifer Van Grove, writing about Twitter integration in Mountain Lion for VentureBeat:
Apple has integrated Twitter into OS X Mountain Lion, the next-generation operating system for Macs announced Thursday and slated for summer release. The decision has profound implications for Twitter and will, should recent history repeat itself, help it dramatically increase signups and tweet volume across the world.[...]
Noticeably absent, however, is Facebook. The companies, we hear, are actively attempting to mend their complicated relationship, but neither is talking openly about Mountain Lion integration.
I'm glad to see that Apple is taking sides here. I've never liked Facebook very much and can see why Apple would endorse Twitter instead. Simplicity is one thing that Facebook does not have and probably never will.
