I agree. Boost is cutting edge, and can help people have some real fun with there code.
Still there are some like myself that are in a weird situation, where their port installation is messed up and they are stuck on an older version of gcc on os x, who would prefer to simply use boost to solve there problem rather than installing a new version of gcc from source.
I actually created my bot using boost, then had to convert all my code to TR1 [again, old version of gcc].
Mind you, I ended up finding a new bug in the process... anyways enough rambling. boost is good, you support it in the last competition, so support it again!
