That being said, I now remember I stopped contributing for a slightly different reason. While I tried to fill WD with complete information about a given subject, this was never leverage by a Wikimedia project - there is certain resistance to generating Wikipedia articles/infoboxes from Wikidata, so you're fighting on two fronts, you always have to edit things in two places and it's just a waste of everyone's time.

Unless the attitude becomes "all facts in infoboxes and most tables come from WD", the two "datasets" will continue diverging. That is obviously more easily said than done, because relying on WD makes Wikipedia contribution a lot more difficult... and that pretty much defeats its purpose.
