Button to deploy Github repos automatically

The team at Nitrous had a clever idea that later was implemented by Heroku too. Every time you create a new development ‘box’ in their platform, they will provide you a button that you can place in any of your Github repos. That button allows any 3rd person to deploy automatically a new development box in Nitrous just with 1-click.

Zendesk encouraging a higher plan

Zendesk encourages to choose a more expensive plan just by emphasizing not only it visually, but also adding a ‘Try’ button that it’s not present in the rest of the plans available. A similar petithack can be found in Animoto’s site.
