I have to say that Github is pretty awesome, and the fact that it uses a lot of the new "cloud" style backend server setup means that the day that they have scalability issues is the day that you should be worried if the internet has such intrinsically. The one issue about git that I'm not comfortable with is the whole explicit branching part of the the design. While for a large project this is pretty easily the "right" way to design a DVS (if for a large / professional grade project you're not explicitly planning everthing, you should be worried), for smaller projects I think darcs' patch dependency tracking approach is much better (or at least much lighter weight).
