If you are in a prototyping, web advertising, etc etc business - sure, your probably just feeding your employer new business strategies to make everyone money. The business is typically fine with experimenting with new ideas hoping to uncover a new money machine - obviously Google's business model is a great fit for this and they seemingly encourage it.
If your doing what Ill call "real engineering" (to ruffle some feathers) on large intricate system this could be a very bad idea. Perhaps you even think your doing the right thing but if you're working within a highly technical environment with many participants you are just going to look immature.
In other words, imagine if everyone at Boeing adopted this strategy as individuals - I think we'd all be opting for taking the Greyhound bus.
