On HN you have access to the world's experts on pretty much any tech (and some non-tech) topics you can think of.
The only other community I've posted to is Reddit, but... It seems like what sets HN apart is the ability to craft and hone your reputation. If you want to become known as an expert in bitcoin, all that it takes is time, intelligence, and writing good comments on HN.
You can gain a reputation on Reddit, but not as easily as here, I think. And it's usually a lot easier to get a negative reputation over there than to gain a positive one on here.
You can also write a profile for yourself, which a lot of people will read. Reddit doesn't have an equivalent of that. Even if you just provide contact info, you still gain value. For example, after I rather publicly lost a bunch of money on Mt. Gox, someone emailed me to see if I was okay. It was a really nice gesture, and in hindsight I'm not sure I'd get that kind of experience out of some other community. But I'm of course biased, since I've spent my time here and not in other communities.
It concerns me that people think this is true. I would bet that HN regulars include very few of the worlds experts on tech subjects; for the most part the world's experts are too busy to hang around on a web forum to chat. That's what makes them experts: focus and hard work.
Which leads to my second point of concern, which is thinking that a person's HN "reputation" means anything beyond HN. I would be very surprised if it does. Speaking of bitcoin, it seems to me that the generally accepted experts tend to be people with a deep history of working on crypto currencies, or at least a deep history with bitcoin specifically.
I've been participating, moderating, and in a few cases researching forum communities for about 15 years. It's easy to fake expertise; just make sure all your comments and posts are well-researched and fact checked before posting. That's not the same thing as being an actual expert--it's the difference between a Ph.D. in physics and an undergrad writing a research paper. No matter how accurate and readable their paper is, the undergrad is not an expert. And forums tend to disproportionately reward readability, humor, and writing style, over substance.
I'm not trying to criticize your posts or expertise specifically; I don't know either well enough to comment. I'm just sounding a general cautionary note about taking online forums too seriously. They are great for entertainment, social gratification, and light education. But they are no substitute for the work of creating real accomplishments.
