Hey Andrew, I didn't know you were on HN. I've been following your blog for a while now and I can vouch for you (for as much as that counts) to the community that you a) are very successful at what you do and b) are very helpful to others in the community.
This guy loves to share and I think it helps him succeed by knowing that he has to share what he's doing. It's a confidence-success loop.
And you're right about 'copycat' - just because you know the process doesn't mean you have the same niche or drive. That's like saying teaching MBAs is teaching a bunch of copycat to all run the same businesses.
