Intagram's website is small? Ok, so show me the large one written in Java. But let's agree: this should really be web site/web interface, not some back-end service in large distributed system like Twitter or LinkedIn, because in such systems there's a great mixture of the whole bunch of different languages. So far list of websites written in what I used to think of "sane Java framework" (Spring Web) is not very impressive [1] compared to Instagram, Washington Post or Reddit.
