This is one hell of a list! I am particularly fond of these ones:

#1 Network sideways - This is a really important one. The lesson here is not to only network sideways. Introducing yourself to the big fish at a conference is frequently a good idea, especially when you won’t have the opportunity to elsewhere. But networking sideways as Li calls it is vital. Those are the people you can really provide value for and they will be happy that you bothered them.
#2 Mostly listen - My wife is very popular. Everybody loves her. Not that there’s only one reason but a big reason is a rule she has for herself: Any time someone asks her a question about herself she makes sure to ask the other person two questions about themselves. She learns more that way and everyone likes talking about themselves, especially when asked!
#5 Be especially nice to the new and terrified - That is something that will never be forgotten by another person. The main reason to do this is to be a good human. But it will also pay dividends for you down the road in a business sense if you do it regularly.
#7 The bit of “black magic” as he calls it - This one needs to be shouted for the people in the back. Take one minute to Google someone and you can learn an awful lot. I also do this when playing gigs. If everyone’s contact info is visible on an email I will look up each person on Facebook. I learn who they are, what they are into, and most importantly, what mutual friends we have. This is huge at conferences, on gigs, in life.

I’m glad I ran across this list. It’s a good one!
