Meteor is just another framework for delivering thick client apps in js which cannot be part of the World-Wide Web, because it doesn't ship semantically described data at a stable URL which can be rendered and repurposed in unanticipated ways. Try
and you'll see a DOM with literally no content beyond "Loading...", completely broken unless you trust their code and want the only rendering it supports.
A quick search turned up http://spiderable.meteor.com/ and a couple of blog links, and none of those have any content either. This seems like an afterthought to the people behind Meteor, and I wouldn't describe them as having an obvious goal of avoiding damage to the Web.
