the latest, over due statistics, there are reasons to be cheerful. Slowly but surely we are getting to the point where half of the Wikidata items have 0, 1 or 2 statements. What is good about it is that the number of items with 0, 1 and 2 statements are all decreasing.
Other statistics are also quite healthy; the number of labels is going up steadily as well. Here too you find that the more popular items grow their reach. They are likely the items people most look for and consequently a tool like Reasonator will happily show its information in *YOUR* language.
In these latest statistics, the quantities make their first appearance. They start with 17,832 statements.
There is a fly in the ointment. We are getting the impression that not that many articles are finding their way into Wikidata. Magnus tweeted a moment ago that "311,479 articles on English Wikipedia have no @wikidata item". It would not be surprising when the number of all articles without a link to an article in another language is close to ten million items. That is a lot and, it spoils the party to some extend.
