What’s going on?
WhoShouldiFollow was designed to help find other interesting Twitter users. It was built by Gary Elliott and Mike Champion.
How does it make recommendations?
WhoShouldiFollow looks at who your Twitter friends follow to suggest new people. By adjusting the sliders on the results page, you can give greater preference in the ranking to less popular Twitter users, or those who are near you.
The algorithm is an item-to-item collaborative filter, somewhat similar to how Amazon makes recommendations.
Hey, why didn’t it give me any recommendations?
If you’ve recently joined Twitter or follow few people (less than five or so), suggestions may not yet be possible. The data used for the calculation is often a bit out of date with your recent activity on Twitter, so you may already follow some of the suggested people.
