How Instagram Hacked Early Growth

Since when is being fast considered hacking growth? I think some of the "hacks" here are really just facets of a strong product and user experience.

Instagram's user experience is/was great--it lets people feel like they're doing something significant and artistic in only a few seconds. I think that's the most important aspect behind Instagram's growth.

Is a strong product a "hack?"

This dogshit should never have been posted. 1, 2, and 4 are not hacks at all. 1 and 2 are simply copying twitter. And cross network posting???

Even 3 is arguable as it's just uploading the photo before capturing the meta. YouTube has been doing that since I can even remember.

This is really stretching the meaning of 'hack'

Since when is following good convention, and doing what you're supposed to do considered a hack?

Don't dilute a potent term, please!

Growth Hacking is apparently a secret word used to Hack Hacker News. Are there other secret words we have not yet discovered?
