Microsoft: Bandwagon Jumper
They know that free software stacks, languages, frameworks, CMSs, etc. are where the market's been going. The vast majority of those are now hosted on LAMP systems.
Microsoft is DESPERATE not to be left behind. So they've swallowed their pride somewhat, thrown a bit of money at open source developers, got them to port open source stuff to run on a Window's proprietary stack. Microsoft is hoping to avoid oblivion by catering for the "developer" demographic who are happy to point and click rather than know what they're doing.
So now we can all look forward to an updated version of the travesty that is/was MS Frontpage: people with the power to create, but zero judgement or aesthetic to know *what* to create (or how to fix it when it goes badly wrong).
