I've got an idea for a few FAQs, but little time to write them:
"How to measure your espresso", where we explain, with pics and all, the steps to reach a decent espresso: you know, the "overfill, sweep, tamp, lock, shot"-procedure.
Maybe a "How to froth milk"? (Not my specialty, though).
"How to blend an espresso?" (Steve, maybe?)
Any volunteers?
