My same question. Reading this thread makes me feel like I am watching a PHP conference host a panel on language design.

Based on the down-votes I'm receiving I have to say I agree.

Because it's interesting and satisfies (at least my) curiosity.

Sure, it may be so, but what does this have to do with hacker news?

"On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity." (http://ycombinator.com/newsguidelines.html)

You could at least read the site's guidelines before complaining.

Somehow I find the diet talks on HN really interesting (but to be fair I don't usually read about that kind of things).
