do you think about ruby on rails jobs?

Not necessarily.

Your question sounds like spam because it doesn't make sense. Ruby on rails is just a programming platform, the question about whether it makes sense to outsource really has nothing to do with Ruby itself, or rails but a business decision that is almost always platform-agnostic.

Because of your inclusion of the rails keywords it sounds like a setup for you to come back and promote some ruby outsourcing outfit.

If your question is serious, then you should expound a bit on what you mean (like I said, it doesn't make sense to me as written at all) and if your point is to come back and spam I don't recommend wasting your time on that, it would be removed.
