Cedric says that Ruby on Rails not being mainstream.

So what?


Go back to this article on Blub programmers from Paul Graham.

If you're an entrepreneur, and need to have an advantage over your competition. Ruby on Rails is a nice one. It's not much, and it's not enough to determine the success/failure of your endeavor. However, it is enough to give you a man power advantage.

While otherfolks can hire teams of programmers to write in JAVA overseas, you'll have a (much) smaller group using Ruby on Rails.

Speed is only good when it can get you somewhere.

Looking at your Blub coder, is Ruby the new LISP? Yes.

Will it suffer the fate of LISP?
Who cares?

If it's for your business, and if it's the right choice, USE IT.

Determining the right choice is up to you and your customers. USING the right choice is up to you alone.
