Obviously it depends on what you're up to, but I think that in terms of startups, I'm much more inclined to trust PG's judgement than this guy's. In the article, he cites "40,000 lines of code" as something that was impressive to PG in an interview, and then bemoans the fact that they may have to "throw out and rewrite most of their code". I wonder if that's the same 40,000 of Zenter code that Google might have to rewrite in any case to make use of Google's infrastructure?

He also complains about reddit, but once again - they certainly "made something people wanted" even if it does/did have its share of bugs (clear text passwords...).

This is one of those things that needs to be balanced. You do have to have something that basically works, and doesn't crash all over the place, but sometimes adding new features or doing other things might be more important than making everything 100% bulletproof.
