That's not even the problem. The Stack Overflow guy wrote a very informative response to people claiming they could clone SO in a weekend (I can't find it now) The core of the problem is not even the quality of the code but rather the thousands of things the site does besides letting you post a tweet and displaying it to other people. Spam protection and protection from people falsely claiming spam on posts they don't like is already enough for me to laugh off the "clone in a weekend" camp.
