I am the "neighborhood lead" for Nextdoor in my neighborhood and I have found it incredibly useful, for a number of reasons: meeting neighbors, unloading free/cheap stuff I don't want to put on Craigslist or Freecycle, learning about neighborhood problems & news (vandalism, construction, permits, etc), finding and vetting service providers (plumbers, landscapers, electricians, etc), and generally staying in touch with people I live near. This is hugely more valuable than the crap I see on Facebook. Nobody posts ice bucket challenge videos on Nextdoor, or kid pics, or game invites. :)

I'm sure this is an exception, but I turned off email notifications when people started discussing how to insulate their apartments to protect themselves from wifi radiation.
I can get behind that. Not to protect myself from wifi radiation, but to cut down on the amount of wifi traffic interfering with my signal. There are only 13 usable channels in 2.4Ghz, and I don't feel like replacing my router for 5Ghz right away.
In the US, there are 11 channels, and either 3 or (with cooperation and planning between neighbors) 4 non-overlapping channels. Investing in 5ghz was the only way I could get a decent signal in my high-rise apartment.
