Josh Porter on keeping focus with a product:

In other words, Instagram has not added any new features with this “largest revamp” to the product. They’ve simply improved what they have to make it even easier and faster to share pictures.

So here’s a simple playbook:

  1. Focus on improving what you already have. Don’t add new features, improve existing ones.

  2. Make what you have faster. It can always be faster. Remove delays (like Instagram did by removing filtering delays…they even now have live filtering)

  3. Improve usability Instagram also redesigned their already-successful photo taking screen. It would have been easy to skip this…

  4. Resist the urge to add new features. Wait until the market demands it or you have real evidence that your business is hurting as a result.

Here’s the thing: What Instagram has done almost never happens!
