If you could integrate relevant features of Google Docs into, say, Twitter Ad Manager, enabling an ad agency and the CMO of the corporate advertiser to collaborate (multiplayer edit, comments, real-time in-app chat, sharing links, version control) on a Twitter ad, it would drive more revenue for Twitter. As the cost in developer time of building those Google Docs goes down, building such a feature would be beneficial to Twitter.
The same applies to many other domains.
Naturally, as a programmer with increased capabilities, your value will go up.
