Occasionally people reply or refer to others' posts in Geminispace, but these threads of discussion are not really visible anywhere. I wanted to make something to help with this, so I wrote a new aggregator that tracks links between posts.
COSMOS is a Geminispace Super-Aggregator that collects posts from various other aggregators and groups threads of discussion together into "constellations". Notably, posts on Station and anonymous comments on Geddit are also shown as part of threads.
The objective of this aggregator is to foster discussion across Geminispace, no matter which corner of it you happen to prefer. Anyone can participate in the discussion simply by posting on their gemlog or any other tracked site.
Threads are formed solely based on links found on pages, so there is no need to worry about which post title you use when making a reply. Linking to any post known by Cosmos will make your reply appear in a thread together with that post. Threads are always shown as a single group of links, positioned at the date of the newest reply.
Aggregating everything into one place has the benefit of finding all the relevant cross-references between posts, but it may also be too much content for one to peruse. Simple keyword filters are provided, currently for excluding or focusing on Gemini protocol/software discussion. One can also choose to only see threads, to better keep track of replies.
