My friendship, if you can even call it that, with Dan wasn't as nearly as tight as others here, but when I decided to finally take an idea of mine seriously into startup territory, I came to Dan for a lot of advice. I was kinda new to the whole thing, and even with such a newbie, Dan always took the time to answer every question, explain every concept, letting me know about problems I will come across, and how to deal with them. It always shocked me how much time he took to help me out. I had only met him through the #startups channel, so we were virtual strangers.
From my minimal interactions with Dan, he seemed like a genuine dude. The phrase 'a real stand up guy' comes to mind as well. He just gave off that vibe and it seems that tons of others here picked up on that vibe as well. The best thing to do is to take a page out of Dan's book in how to treat others, and be selfless, and spread that. I know I'll try.
We didn't know each other too well, Dan, but cheers to you, man. And my prayers go out to your friends, family, and Tom.
