70 tabs is only normal in the group of people reading HN. Other normal things for that group of people would be having a compiler installed on their OS. Would you describe having an installed compiler as normal for the general computer-using population?
I'm willing to bet that the vast majority of computer users don't ever have more than 5 tabs open at any time.

Totally off-topic, but Yes :-)
.Net has a compiler built-in (you may need the SDK to get the command-line version), many systems have a compiler for a shader language, and your packet filter may ship with one.
