Immersion is an invitation to dive into the history of your email life.

BlinkLink – A “blinklink” is a URL which disappears after a certain number of views or retweets. It seems to be designed for images and videos only, so just upload your image or video, specify whether retweets can be included in the number of clicks allowed, and it will then generate a unique link for you, which will expire after 100 views. 10 more views can be gained by tweeting the link.
