@wesm @y-p good addition?

It's a good start, though I suspect the format will ultimately limit this from growing beyond
a certain point.
Also, you're up against google/stack overflow for discoverability and that's a hard fight.

Possibly a pandasfu.me site in the future? a cross between a cheat sheet,
http://repl.it/ and commandlinefu.com.

Suggest putting the word out on the mailing list and opening an eternal issue
with a "good first PR" tag. EDIT: since merging the PR will close this one

Keep knockin'em down, jeff. 👍

ahh....but NOT trying to compete against stackoverflow, in fact lifting links to 'interesting' use cases....
sort of supplemental documentation....

Oh sure, it's just a question of what people reach for when they hit a problem.

[jreback]

providing options!

@y-p what do you think of cookbook? (it just updated)

[ghost]

Shaping up very nicely.
