My exact thoughts. I think I am going to print it out and study it for a while. I am sure there are tons of productivity things I can learn..and things I should probably already know.
For intimidation, try browsing all the help pages of vim! :-)
I've concluded that vim has every feature I can imagine - and then some. But I can't appreciate it until I've imagined it. The problem is that it is impossible to find that feature in the help, since I don't know its name. Google helps here, by searching for a description of it in my own words.
Every tutorial I've ever seen on vim is mind-bogglingly boring. I've learnt the most by just hearing one tip at a time - and searching for one when I need it.
Some people can absorb massive quantities of raw information, but I need to integrate new information into my other knowledge in order to be able to use it. Then there's practicing the habit of using it, and learning in what situations it is appropriate. For a tool, it's not knowledge per se, but the application of knowledge that is useful.
