Hmm. I don't know about serving "99% of developers" without support for at least top 10 languages/frameworks, catering for enterprise (which is, in my country, like 50% or more of all jobs for software devs), and an IDE that has at least the most basic of features... but most of all, I do not feel like the blog post or the site itself communicates in any way the two most important feelings I'd like to get as a developer: 1) I'm in control if I need to be, 2) I understand what's going on. These are of course related, but I have neither the sense that I can control things here, nor that I understand what's so special about this. For working alone my own dev machine is better in every regard with the exception of being able to code away from that machine; for working together I would never let a 3rd party provide glue and choice of architecture, security etc. anyway, since anything bigger would likely be a more serious (not more frivolous) endeavour... what am I not getting?
