Starting with nothing and building everything from scratch is the opposite of what Mimosa is trying to do for you. The idea with Mimosa is you are coding straight away rather than hunting down plugins/modules, or finding generators ;), and then figuring out how to configure them. All those compilers are available, but if you don't need, for instance, TypeScript compiling, then the TypeScript stuff stays out of the way. No harm having those extra things.
Mimosa lacks Bower integration, though. Bower integration is nice for managing those sorts of things.
If I failed to do so already, please allow me to state that yeoman and its generators (including my generator) as well as Mimosa may very well be an "expression of opinion" of various developers. The opinion is regarding what makes a productive workflow. This will certainly change over time or, at least, on a project-by-project basis.
In a different comment I made on this submission, I mention that if you are a developer that has worked with Jade, CoffeeScript and LESS - and enjoyed doing so - then my generator may make the process of getting up and running with them a bit faster for your next project.
Mimosa author here! I'll work on the website. =) I do think the tool is better documented than some of the others, and I was really going for having the docs rather than making them super pretty.
Mimosa is very pluggable (http://mimosajs.com/modules.html), moreso than Brunch, but slightly less so than grunt, though, to be honest, my grunt experience is slim. That said, grunt obviously has quite the ecosystem of plugins that all the others lack.
HackerNews commenting n00b, but guessing it only lets replies go so deep? Hence my reply to the site suggestions goes here. =)
Crazy kinds of awesome to get that kind of feedback! I'll take a look at all that stuff. Big site update content-wise with my next release and I can make some changes then.
Hacker News has exponential delay time on comments based on depth. So the deeper a comment is, the longer you have to wait to reply to it. It's supposed to help cool off flamewars.
Your site definitely looks slick! I'd take any suggestions anyone has and as long as they make sense, implement them. I'd rather be writing node than thinking about design anyway. =)
