I buy into the ethos that HN is an echo chamber and, in private, many here have agreed with me. In fact I'm almost certain the reason I was forced to create a new account here after over a year in good standing is because I rejected a handful of this echo chamber's views. That said, I still value HN and like it but have learned to filter out a lot of the bad stuff (which keeps on coming faster and harder lately).
I also think a lot of what you said can be applied to the B2C space:
B2C is is boring as shit and not even remotely interesting.
The only challenge to setting up a competitor to Facebook/Twitter is that it's so mind numbingly dull. B2C programming is an utter pile of mind-numbingly boring crap. It's not sexy because it's incredibly simple with a colossal amount of edge cases. B2C is mindbogglingly complex simple software.
B2C is just the edge cases.
It's not the remotest bit challenging to most people. It often lives and dies by the latest fad and undeserved hype in tech blogs.
But you'll get a lot of VC funding.
Do you want to read about it? No, because it's so ridiculously shallow and played out. That's why everyone's sick of it.
(disclosure: I'm actually writing B2C software (no, really, I seriously am, not joking or being sarcastic at all there))
Sexy is in the eye of the beholder. If you characterize all B2B software like Quickbooks then yeah, it'll be boring to most people in the same way that yet another social network, geo-whatever, so-lo-co-mobile app is going to be boring to most people. You're right about the edge cases when you label them as edge cases. But if you think of them as niches then it becomes interesting again and a whole new market is laid out before your eyes.
Your whole comment was very general and you seem to apply your personal opinion to "most" people. I do get what you're saying and I can see how a lot of B2B products can be boring to a lot of people but the way you put it makes your argument weak.
