fediverse.space is a tool to visualize networks and communities on the
{' '}<a href="https://en.wikipedia.org/wiki/Fediverse" target="_blank">fediverse</a>.
It works by scraping every instance it can find and aggregating statistics on communication
between these.
</p>
<h2>FAQ</h2>
<h4>Why can't I see details about my instance?</h4>
<p className={Classes.RUNNING_TEXT}>
Currently, fediverse.space only supports Mastodon and Pleroma instances. In addition, instances
with 5 or fewer users won't be scraped -- it's a tool for understanding communities, not
individuals.
</p>
<h4>How do you calculate the strength of relationships between instances?</h4>
<p className={Classes.RUNNING_TEXT}>
fediverse.space scrapes the last 2000 statuses from within the last month on the public
timeline of each instance. It looks at the ratio of
<code>mentions of an instance / total statuses</code>.
It uses a ratio rather than an absolute number of mentions to reflect that smaller instances
can play a large role in a community.
