StreetPass is a browser extension that helps you find your people on Mastodon. Here's how it works: 1. Mastodon users verify themselves by adding a custom link to their personal site. 2. StreetPass lets you know when you've found one of these links, and adds them to your StreetPass list. 3. Browse the web as usual. StreetPass will build a list of Mastodon users made up of the websites you go to.
