I built one (semi major) project in meteor because it looked cool and easy to spin up - which it was.

The problem as stated here was that when there was a chrome update, iron-router broke and spent quite a bit of time trying to figure it out.

Not to mention that shortly after I got it fixed one of the only hosting solutions that I had it hosted on (modulus.io) went under and so did my app.

It was brutally frustrating. Saying that, I would probably use it again in some sort of hackathon or startup weekend, but not anything of scale.
