Talked to some folks around here and:

1. It’s ok to use double-quotes.
2. We’ll be switching to handing out example code with double-quotes in it.

Cheers.

Did anybody get back to you re: single quotes vs. double quotes?

If not, I’d appreciate it if you’d try double quotes and let me know what happens.

If it turns out alot of people are using strategies that only work with double quotes due to, um, competitive history, then, this is probably a change we want to make, so thanks for pointing it out.
