Mastodon is an open source social networking platform for microblogging. While it has a web-based interface, many users prefer to use a client to access Mastodon. Clients are programs or applications that allow users to access and interact with the Mastodon platform from various devices, including computers, tablets, and phones. I moved to Fosstodon in 2019, and it has become my primary social networking site.
Like most users, I started using the Mastodon web app by pointing my browser at joinmastodon.org. I found an instance to join, created an account, and logged in. I used the web app to read, like, and reblog posts from my favorite Mastodon users. I also replied to posts without ever having to install anything locally. It was a familiar experience based on other social media websites.
The disadvantage of the web app is that it lacks the richness of a dedicated Mastodon client. Clients provide a more organized and streamlined interface, which makes it easier to navigate, manage notifications, and interact with others in the fediverse. Clients also make it easier to find and generate useful hashtags, which are essential to sharing your message in a non-algorithm-driven environment.
