Might have been different if they had chosen to embrace SQL, instead of just putting it on the roadmap and letting it rot.
It's a pretty narrow full stack to me if you don't have real support for sql databases. It's been sitting there for 3 years and has about the highest votes of all them. They had a post about experimental postgresql project in august(http://info.meteor.com/blog/an-early-look-at-sql-in-meteor), but it's mostly sat there with a few updates since then. It doesn't seem to be much of a priority.
If they were serious about the framework they'd drop everything they're doing and focus on getting some proper relational support happening ASAP.
