FYI, Mithril is largely a scratch-my-own-itch kind of project project and I use it heavily at work, so I'm definitely not going to walk away from it :)
But what if you're in a Starbucks, and the person behind you is the head of BMA Model's hands and feet division? (http://www.bmamodels.com/hands_legs_feet). As you reach for your frappachino you're "discovered" as the next-big-thing. About to explode into the glamorous, yet high stakes world of hand-modelling. It's a multi million dollar deal... but with the stipulation... no more coding effective immediately.
What happens to mithril then Leo? What then?
If it happened at facebook they'd give the job to Jimmy "Stubby Fingers" Malone and move on.
Obviously I'm teasing (hopefully at least).
I think there are actually a lot of advantages to your running mithril lean & (mostly) solo.
You contribute and participate in all those places and even turn up on HN.
It does make it a consideration when selecting a direction for a project though. It's a bit of a risk awareness/tolerance thing. I still think C# is way better than node.js for some things too :)
