What next?

My opinion is that Ruby is way better then Python :). I find the syntax is better.

i guess it depends what your goal is, if its just to complete tracks then I guess do whatever you think would be most fun.

Why not make a start on one, its nice sometimes to get stuck into a little project and reinforce what you have learnt, sometimes when I learn something then move onto something new, I start to forget what I did previously unless I have done some little projects to make it really sink in.

Since you've already put the effort into learning Ruby, why not apply that towards Rails so you can use it to build the kinds of applications you'd like to build? Putting that Ruby skill into practice with Rails, and then flexing your Rails muscle by building some sites (like a simple social network or to-do list or what-have-you). Perhaps you could even take a look at Treehouse's new course on Ruby Gems (or is that an upcoming one?) and contribute a gem!

Once you do that, you can take a peek at Python. Once you are familiarized with Python's syntax and idioms, you can poke around Django (a web framework, like Rails) and build something with that. Since you'll be coming from a Ruby/Rails background, picking up both should go faster.

I suggest sticking to Ruby only because I myself have a weakness for becoming infatuated with newly discovered languages, or languages/frameworks/whatever I know of, but haven't tried. The result is... Well, I lose track, and wind up with a bunch of half-built side projects and only a cursory knowledge of things, rather than a deep knowledge. It's nice to have a wide breadth of knowledge...but it might be more important to have some completed projects you can show off.

I suppose it all depends on what you want out of your education here. :D

Kenneth Love is amazing. You'll enjoy Python, going through his courses.
