Here is proof: http://news.ycombinator.com/item?id=56758 http://news.ycombinator.com/item?id=56758 (Paul Buchheit was GMail's creator and lead developer) Also, here is more proof: http://news.ycombinator.com/item?id=190151 http://news.ycombinator.com/item?id=190151 You could tell me: "OK, but it doesn't prove that current GMail is not in GWT. It may have been rewritten". I'd answer that: - using firebug and looking at the js scripts loaded by GMail, there is no trace of GWT (things such as *.nocache.js scripts). They might have obfuscated to hide it, but why do that? - if Google indeed rewrote GMail using GWT, they would have announced it, like they did for Wave / Adwords.
