One of D's potential massive wins is speed and I think that has 
the most easily conveyed impacted on the audience. If we had the 
best benchmark site for a very large range of languages it would 
not only draw people here but drive the improvement of D on all 
compilers (and perhaps allow us to make LDC/GCD for run speed, 
DMD for compile speed more explicit) as every time there is a 
benchmark contest we seem to find some small thing that needs a 
fix and then D blows others away. This would also convey more 
idiomatic D for performance as D seems to suffer from people 
writing it as whatever language they come from. People love 
competitions, the current benchmark site that seems to weirdly 
dislike D is one of people's go to references. I do not have the 
ability to do this but it would seem like an excellent project 
for someone outside the major development group, a Summer of 
Code-esque thing.
