Comprehensive? No. Nothing even comes close to the scale that reddit has for the niche that Reddit has.

For local things, consider instead Facebook groups and nextdoor... not that I think that those are good alternatives. There may be a slack channel or discord group too - though those fill different (but often similar) roles.

One of the issues that you'll see with this is that you'll need multiple accounts to handle the disparate sites (well, many of them have a sign on with Google or Facebook) - there's no "one stop spot for everything".

And despite claims of power hungry mods on reddit, it becomes clear why something is needed if you spend any time looking at Nextdoor and Facebook.
