Zend and Microsoft have done a lot of work in the last year to make PHP run well on Windows. I never understood why Microsoft devoted resources to that, but now it is clear: it’s going to make technical integration between the two organizations go much more smoothly.
Maybe now somebody will release a .NET OpenID 2.0 library that actually works.
Big losers here from a tech supplier perspective: FreeBSD and MySQL.
Another potential big loser is Adobe; having a gigantic global audience will help with adoption of Microsoft’s various Adobe-killing initiatives like Silverlight, which would never otherwise have penetrated the consumer web without a large built-in audience like Yahoo’s.
