Mainly that Firefox has telemetry enabled by default and you have to go into the settings to disable it.

It would be great to have a way for communities to voluntarily marge and consolidate once things settle down. I can already see a lot of fragmentation of topics that honestly are never going to be big enough to sustain multiple communities. The flip side of that is that rogue mods could abuse that to merge unrelated subreddits, I guess.

Otherwise, “multireddits” would be great, it was the main way I accessed the other site.
