Especially in the tech scene, a lot of people see themselves as unappreciated geniuses. The idea that there's a good, simple alternative that will get mass adoption that they haven't thought of doesn't fit that narrative. There must have been a reason they already dismissed the idea, so they approach it skepticism. (The money thing is related to this - unappreciated geniuses deserve a good get-rich-quick scheme, after all.)
Parent suggested that despite this there are only ever thirty articles on the front page at a time, so we shouldn't see more finance ones.
I pointed out that this just means that the ratio of finance stories within that thirty is likely to be higher.
No. Parent's point was the same as yours: numerator increased and denominator unchanged implies fraction increased.
Recently I've been finding that my twitter feed is a much better way to get my dose of hacking related stuff -- if you follow the right people it's wonderful! (It's kind of sad that I have resorted to that though, since HN did open my eyes to a lot of things back in high school.)
I personally come here for tech related stuff (not an entrepreneur, don't particularly care to become one) but still find myself getting caught up in the latest funding BS news. Unfortunately, SV (and HN) seems to be getting watered down with a lot of money-chasers. Of course, I am sure someone, somewhere was saying the exact same thing 30 years ago, so whatever...
That said, I think I know what the culprit is: money. Check out the headlines on the front page. How many titles contain a '$'? Yesterday I saw some big numbers: 100M for github, 20M for stripe, 10M for someone else, plus kayak IPO numbers. Today we've got kickstarter.
As a community, we've become obsessed with money. Bootstrapping revenue, angel rounds, VC funding, acquisitions, IPOs, croudfunding, etc. When people focus on money they get upset. There are a myriad of reasons for this, but the quick version is that it's human nature and basically unavoidable.
So, in short: we think too much about money, and as a consequence we're grumpy.
