#request #idea (user-)bot to summarize what goes on in a group.

@topics_bot was this, but it no longer works?

limitations:
- normal bots can't see previos messages posted before it was aded to the group

features:
* participants (count + main ppl)
* topics (words / phrases by rank(num))
* high level (conversation count?) (how?)
* other metadata:
- counts
- entity summary (links, media?)
* ignore noise? (shitposting?)
