Stephan T. Lavavej. He's a standard library guy at MS. He's around
here from time to time, but also makes C++-related videos for MS's
Channel 9 PDM (propaganda distribution mechanism).

Sure. It is MS in general, not Herb specifically. If Herb wasn't
there, it would be somebody else. However, Herb is the face of C++ at
Microsoft, and he repeatedly refers to MS's supposed commitment to C++.
  Actions speak louder than words. Forget all of the careful marketing,
and just implement the d*** language. Doing so would engender a much
larger amount of goodwill towards MS over time.

For the record, I believe GCC's rampant use of extensions is also
detrimental. Obviously, if all or most compilers implemented the entire
language, extensions can be disabled, and the standard library 100%
works without the extensions, we'd be far better off than we are now.

However, the presence of language extensions cause people who target a
particular compiler to use those extensions. The problem with this is
that C++ development should not target a particular compiler. If C++
development did not *have to* target compilers (as it does currently),
then feature extensions become meaningless, and portability ensues.
Furthermore, compiler extensions tend to be far less thought out than
actual language features, and, even when the basic idea is good, the
presence of the existing extensions interferes with standardization.
E.g. typeof vs decltype.
