The article's bullet points are great, but I would emphasize one thing:
Don't be afraid to ask, but only AFTER YOU'VE DONE YOUR HOMEWORK. People can be surprisingly helpful, but especially if it's clear you're working hard to make each request count. They're much less likely to think you're wasting their time if it's clear you've been hustling and see their help as a catalyst for you working EVEN HARDER.
That reminds me a lot of ESR's "How to Ask Questions the Smart Way". Two variations of a general rule, I think: if you want someone's help, make it as easy and hassle-free as possible for them to provide it.
