But see, I don't think motivating someone to help you is really that hard. As I mentioned in there, there are so many places where there's oodles of people who'd love to help. Want to ask Alexis Ohanian something? Pay attention to when he hosts another AMA on Reddit. Or use Clarity or Public Beta. Or really just email them. I answer a ton of questions I get over email.
There are a couple reasons though sometimes I don't reply to an email "looking for help":
1. The email is thousands of words long. I don't have time to read that. Very few people do. Keep these intros and notes and questions to 5 sentences or 500 characters, or try your hardest to get close.
2. Ask something. I get too many emails looking for help, but when you read the email, there's isn't actually a question inside. What do you need help with? Be specific. "Feedback" is way too open. You want Feedback on design, or features or marketing or what? It's best to focus me on something so I can save time figuring out how I can actually help you.
And if you really want to use some extra encouragement to get people to help you, flattery gets you everywhere. Mention what you've been reading of theirs. Quote their stuff on Twitter.
Also, I see too many people that say something like, "No one wants to help me." Everyone WANTS help; to get help you need to give some. Start networking like crazy, find out what someone else needs and provide that. It takes time and dedication, but you will be reciprocated.
So ask for help, but don't waste their time.
Also, "help" doesn't have to be a one-way street. Maybe the person you want to meet is coming to your town and needs a ride from the airport.
