The number of folks here and on reddit and even back to Slashdot who had and continue to have negative reactions to incredibly popular things shows that it's really hard for techies to predict what will become a success. I don't think we're irrelevant or out of touch, I just think we really are in a market all our own.
Look at the overwhelmingly negative response to the iPod, which then went on to destroy CD players and every other brand of MP3 player, right up to the point where people just used their iPhone for MP3s, when the techie audience bemoaned the death of the iPod because their music library was too big to fit on a cell phone, at which point the mainstream switched to streaming services so no one noticed. Luckily there are still niche products catering to our needs.
Look at the complaints about the iPhone with no multitasking and no physical keyboard and no user-replaceable battery and no stylus, and the massive success it had which ultimately killed Palm, Windows Mobile, and Blackberry. Luckily there are still niche products catering to our needs.
Look at the complaints about the iPad, which killed the techie-favored netbooks. Luckily there are still niche products catering to our needs.
My rule of thumb is, if HN/Reddit/etc hates it because it doesn't have enough features, it's going to be a massive success in the mainstream market.
