Gmail was the first single page application I remembered using. It was eye opening to many people what the web could be as an application platform.

Even the spam filter was smarter and better than everyone else’s for a very long time.

Part of the trend of needing to dumb down everything by removing "power" user features because we can't trust non-computer savvy users to not self immolate their data.
