Having said that I can't help but think how strange it is that the launch of another word processor is novel enough to reach the front page of HN.
I understand that the co-founders are big names in the valley but a word processor? Perhaps I'm missing something but the technology here seems anything but front page worthy.
I'm getting pretty tired of these "how does this belong on HN" posts. Face it, most things in computer science have been invented before. The interesting thing is how well a product has been executed. Should we not have linked to the announcement of Facebook or Dropbox when they were announced, just because social networks and file syncing products were around before them?
It'll be hard to convince me that in only 400 years of its existence we've managed to exhaust the majority of our capacity to expand computer science.
