If you want to be truly intimidating...

The sad thing is, I like a lot of his music so the fact that I was truly intimidated by posting a link by him for fear of what my friends might think of me probably says more about me than it does him (and perhaps speaks to a bit to why Rdio and Spotify had to add privacy controls). Oh well! I'm intimidated by music snobs, I guess. I'll be intimidating another time.
Personally, I find the notion of a guitarist boring. I like music, not guitars played expertly.
I had the same reaction when I read this a few months ago:

That's a strange thing to do.
The result is that very few people trust very few people (and that trust is not very large, its more of a way 'i know this guy who do XX because I have leverage').
That's sad. Working in a sincere environment, with good values, is so much better on so many accounts. And it also pays off. Have courage. Be sincere.
But I agree with the post. It's worth it to be sincere. Even when those around you may not be expecting it.
