Following Joel's advice may or may not make you better off. Can't really tell without going into technical specifics. Can you tell us more about your case? Our current product (online mapping for corporate clients) went through multiple rewrites when it was already quite successful: the client side went from JavaScript to AS2 then to AS3, the server side went from PHP to C#, and in addition to that many big parts of the project were rewritten from scratch multiple times. None of this was ever done just to "incorporate best practices", though.
