ReadingPack enabled you to follow other people's reading lists and recommend great articles you recently read. Like Pocket, but social.
I built ReadingPack from the ground up and worked on it full-time (bootstrapped). I did everything from product design, frontend, backend, marketing, and support. ReadingPack started as a Chrome extension but later on, I added other tools such as mobile apps, more extensions (FireFox, Opera, and Safari), and integrations (e.g. IFTTT integration, Spritz, etc).
After almost 2 years and hundreds of weekly active users, I ran out of money and decided to stop working on ReadingPack.
ReadingPack on Lifehacker: ReadingPack Organizes Articles to Read, Helps You Discover New Ones.
As a new user, it was critical to make sure you will complete the following stages in order to fully understand and get value from ReadingPack.
The feed was the main place to discover new articles to read, based on recommendations from people the user follows on ReadingPack.
I built an algorithm especially for the feed so the first articles were the most recommended by people the user follows, considering (1) how many people recommended them, and (2) when the user saw them for the first time (if an article appeared a week ago and the user expressed lack of interest, the importance of that article will decrease even if a lot of people recommended it).
