IMHO, the differential key of Cypher regarding to SQL, is the way in
which Cypher builds the "joins". I mean, the clause PATTERN or WHERE
written like "lucy-[:ACTS_IN]->movie<-[:ACTS_IN]-co_actor" is pretty
powerful. The rest of the details are unimportant, in the sense they
already have an equivalence in SQL. So, I think to use SQL-like
queries could attract more people interested in Neo4j. And at the same
time, this people will discover the versatility of the Cypher JOINs.

Regards.
