Depends on 2 things for me

1) quality/value

2) integrity of person providing it.

2 extremes:

a) a life coach selling help!! I'd head for the hills in most cases as for me most of the information they sell is quite obvious to me.

b) #[2] providing his owm thoughts on bitcoin. Clearly his thoughts aren't the same as what you get on wikipedia. I'd pay (and have bought his book) for his knowledge. Quality/value is high and he has integrity (he goes to many conferences and doesn't charge speaking fees etc. He is in it for the world).

Information isn't information in this crazy world.
