What web-development platform should I use considering Time-To-Market?

Question

I have been looking at a few differend platforms for my coming web-development project. I would like to hear what web-development platform is recommended when considering Time-To-Maket. Suppose that I already know the programming language well, but not the web-framework. The OS will be Linux.

My requirements and priorities:

• Time-To-Market
• RESTful
• Maintainable code
• Scales-up (not dog-slow)

The one I have looked at but never used are:

• Java and Play! Framework or GWT
• Python and Django
• PHP and Zend Framework
• Ruby and Ruby on Rails
• Erlang and Nitrogen and Webmachine
• Scala and Lift
• C++ and Wt
• C# and ASP.NET Mono

It's a bonus if the framework has support for making sites for mobile phones.

Answer 1

If time-to-market is your primary concern, and it is just you developing it, then you should choose the framework you are most familiar with already. (Or the one that uses a language you are already familiar with - surely you don't know all of them ;)

Answer 2

If you're the only developer, Sosh is right.

Generally speaking, Ruby on Rails or Grails are probably the best candidates as they're all about productivity (DRY) and getting the product out the door (although not mandatory, usually used in an agile process).

They might require compromises in terms of performance, which you stated as one of your priorities.
