Q. What do Twitter developers actually do?
This is a useful feature, but I'm amazed at how slow progress is at Twitter, Facebook etc. Considering the size of their development teams, they don't seem to actually *do* a lot.
Does building the infrastructure, creating new optimised database etc really take up all their time? I guess it must, but it never fails to amaze me how large teams can put in so much work with so little to show for it. I'm a developer myself, and I know how much a small team can do when they put their minds to it.
