In defence of that statement (although I'd agree it's a bit strong wrt Meteor's current state) the vast majority of web apps can get by with Mongo and without SEO (Google can't cache pages behind a login anyway). For a young framework it's come an exceptionally long way, and I haven't hesitated to use it in production for those use-cases that fit. It's just... yeah, important to note that not all use-cases fit (and they probably don't need to--I'd rather see them focus on what they're good at and be upfront about it).
