Scalable framework for web apps?
qhoxie: I'll give my top recommendation for each language you named.  I have used all 3 of these with great success.  I have also used competitors for each of them.* PHP - Kohana* Python - Django* Ruby - MerbI used many PHP frameworks a while back and eventually settled on CodeIgniter (which is very good).  After Kohana spun off from CI, it began to gain advantages and has continued to.I've used Pylons and TurboGears before settling on Django.  It's quite fast, and can be made faster when paired with psyco.I used Rails for a long time before approaching Merb.  I have followed its development since shortly after the pastie that Ezra made of the initial code.  Merb is making a lot of great choices and is and will be my framework of choice.
