Drowning In Information

Drum has some questions about last Friday's document dump:

This data dump includes everyone who's been on a public tour of the White House?  Everyone who's been invited to some kind of White House ceremony?  Seriously?...This is kind of ridiculous, isn't it?  I suppose it's easy enough to filter out the dross once you figure out the right codes, but it almost seems like the White House is deliberately trying to inundate everyone in useless mountains of data by including this stuff.  In particular, when the end of the year rolls around and we get the full dump, do we really need the names of all 500,000 people who have been on a tour of the residence?  Is it even right to make all these names public?  Is the White House staff playing a quiet little joke hoping for a few reactions like this?  What's going on?
