As open source users, we sometimes seek for help and sometimes offer our help. There is a Neo4j tag on StackOverflow, https://stackoverflow.com/questions/tagged/neo4j, for all the Neo4j questions.
There are several Slack channels; see https://neo4j.com/developer/slack/.
If you use Twitter, follow them all: @neo4j, @mesirii, @emileifrem, @rvanbruggen, @craigtaverner, @Aethelraed, @darthvader42, @tb_tomaz, @lyonwj, @maxdemarzi, @markhneedham, @BarrasaDV, @ryguyrg, @andres_taylor, @iansrobinson, @apcj, @jimwebber, (and maybe @wadael, too).
Graph Connect conferences and local meetups are a very good way to meet fellow graphistas, exchange tips, and push job offers.
