Just hooked up bird.makeup to tracing software for the first time and it's really fascinating!

For exemple, this is an histogram of how fast Twitter answers queries for recent posts by an account.

Look how slow it is! There are a few speedy one at 50~ms, but most are >300ms, which would indicate that they are not cached.

I would have thought it was the other way around, most accounts cached a few that have posted recently that are not cached
