I think no one would disagree that the current viewing experience on the main
wikidata.org interface is not ideal. Keep in mind though that this is fundamentally an impossible UI task. There are many many different ways that the data about an item in wikidata might be best used/viewed depending on who is doing the viewing and why. Having the same interface attempt to support viewing data about astronomy and art history is just never going to be great for either. While I applaud and encourage the ongoing development of the default interface, I think it would benefit the community to think past that interface to the kinds of purpose built wikidata-driven applications that serve and benefit from specific communities. Anything we can do to make it easier for people to build good apps (in addition to those in the MediaWiki family) that read and write to wikidata could have a huge impact on its ultimate impact.
One of the things that freebase (RIP) did in this regard was the Acre [1] hosted development environment. While clearly it didn't tip the balance for them, I think it was a powerful idea that we could probably learn from.
