You don't have to install RVM, but it does help. It was never that difficult for me, but I use OS X for Ruby dev mostly.

And there may be a variety of ways of doing things, but that's because (1) Ruby has been more well-used than Go, and (2) it has more flexible loops, etc. to make it less verbose, and yes there are a variety of ways to add methods, attributes, etc. but after you spend a little time to understand how the Ruby object model works, you'll understand why- almost everything is an object. Also, the language has evolved, so there are some differences in syntax between 1.8 and 1.9 but you can still use 1.8 syntax in 1.9.

Yeah agreed Ruby is more powerful especially with loops. The object model and that methods are messages passed between objects is also great, once you understand it.
