I recently asked <https://twitter.com/thadguidry/status/1247635376094707712>
a Freebase colleague @narphorium to graciously spend some time to write up
what was once a very cool Freebase app that many of us used in Freebase to
see overlap of Freebase Properties (like WD statements) between 1-5
Freebase Topics (like WD Items) that then ran a query to find other Topics
that matched that overlapping set.
I thought that sharing this knowledge would allow others to get inspired
and learn and possibly build a similar shape tool for Wikidata; if not
Best of luck WD engineers!
