Having built two apps in the last two years using Rails (one making front page on Hacker News and has 10,000 plus users), there is a sweet spot that Rails hits that other frameworks don’t.

The fact that you get so much out of the box that just works and you don’t have to do much beyond configure it reduces a ton of headaches.

Absolutely would rather be using Go instead of Ruby but for apps of a certain kind and size, the omakase approach of Rails still wins out.
