This startup: https://www.kashoo.com/home https://www.kashoo.com/home was built by a husband doing all the tech, and a wife doing the non-tech part. The app was written using Java and GWT. Can the husband roll faster if it was using Rails? probably but not significantly. Another anecdotes: I was part of a team of 3-4 developers delivering a portal solution for British Columbia compensation board (WorksafeBC, http://bit.ly/1QhUH8L http://bit.ly/1QhUH8L NOTE: it's a few pages of PDF to show the size of the app). The thought of Java is slow, not agile, and probably overkill for small team, small project, small this and that is probably not warranted. I've mentioned this in another thread: choose Java and you'll set for at least 5-7 years with minimum problem, focus on solving business problems and less on infrastructure, upgrades of software/libraries, choices of latest du jour). Those open source libraries are damn solid and I very rarely need to worry much whenever I upgrade those libraries. Open the pom.xml, bump up the version number, sit back and enjoy the latest version. Do you want to write a mobile app? 1/2 of the popular platform is already covered with Java so you just have to worry about the other one. I'm having a very very hard time justifying the use of Go for "Web Application". I just can't see the benefit over Java (I'm scoping this to just those 2 platforms).
