No, David isn't at RStudio.  He was at Revolution, but it was bought 
(assimilated?) by Microsoft, so he's there now.

After getting some "can't load" error messages, I discovered that the installer had updated the MicrosoftROpen.app, not the "vanilla"  R.app . Is this expected behavior, or am I making a hash of my apps and libraries by trying to keep both R and MRO available on my (Yosemite) machine?

If it really did upgrade your MRO app then it means Microsoft doesn't even bother changing the ID of the app which means they still claim it's our CRAN R which sounds really wrong given the name...
