This tells an interesting story about good "looking" but not adopted software. At a cursory glance, this looks great! All these datasets online! How wonderful.
But once you start to dig a bit deeper and scratch the surface, just barely, you can see that it's actually a graveyard of an open data era gone by. Many of the datasets here look like this:

Where they were initially placed online, perhaps with an attempt to be more transparent and open to the public, and they haven't been updated since 2012. The political points got scored by the elected officials and appointees, but either the software that the career bureaucrats is too burdensome to use, or the will to be open to the public just isn't there.
After spending 10 years in this field, That's the primary problem with these transparency efforts. They sound great to the public, and great to the politicians, but nobody bothers to sell the staff of government on why it's important. And when they don't want to do something, or when they're not sold on it, it just doesn't get done.
Software designers and "civic hackers" need to grok that to be successful their first customer isn't the public or the politician, it's usually the career civil servant.
