What will qualify as a great company? Is the deciding factor that it does decent revenue or that it uses a pretty nifty technology stack or is it that it does decent revenue in which the technology stack is an enabler?
Zimbra - Well, the point is that Indiatimes did outsource it. Guess I gave you an example that you asked for there. Same is the case with NDTV and Tekriti. They may not be to your liking, nor am I sitting in judgement whether they are 'great' or not, but the fact is that you can build good companies and businesses either way - build or buy/lease.
Coming to what you have said, " As for failed startups, you will never know as a lot of those stories just die with the companies," this is precisely what I am trying to address. That, you just don't know what their reasons are. Just like I would not be able to tell you what is best for Infinitely Beta.
I agree with a poster above, that the blog linked here is written by an immature person.
