1. Boost isn't sexy any more. As one very highly respected world famous engineer put it - and I won't say who, and I apologise to him for stealing his words without attribution:
"Boost used to be about all the stuff you really wanted in the standard. Now Boost looks like all the stuff that wasn't good enough to get into the standard"
I feel like the professional programming community is always 3 to 5 years behind in using the latest and greatest technologies. If there were a Boost v2 today, I imagine people would already be experimenting with the stuff before it actually made it into real work projects 3 to 5 years down the line. By that time, I suspect most every developer will be using C++11 or better. Quite frankly, I'm kind of surprised that this Boost v2 concept hasn't already taken hold of the Boost developers. The thought of getting rid of anachronistic programming styles and idioms from source code that's going to only be used by the latest compilers should excite all library developers. I hope a Boost v2 project does come to fruition. I disagree with one of the writers who claimed C++ was no longer sexy. I think the new C++11 features has definitely made the language sexy again.
