Any Anti-Facebook service needs at least a good "News Feed" like Facebook does. EveryBlock had a really awesome and useful news feed. You'd see all the new permits(film locations, building, zoning, etc.) issued, crime reports, comments about community issues, events, etc. in your neighborhood. It was exactly what I thought of in terms of "hyperlocal" news. It was extremely useful even as a passive user.
NextDoor just isn't any of that. They don't have the same News Feed quality that EveryBlock had. NextDoor posts are like "I have a new Ikea desk I'm trying to get rid of" or "What's happening at 20th and Mission"-style Twitter posts. Not very informative or useful.
