A few changes.

Things 150, 200, and 250 years ago are outside the expressed target range of the blog, so we're discontinuing posting on those events.

For the most part, at this point, things 100 years ago, which would be 1925, are also, so we likely will discontinue those as well. 

Things 80 years ago and 50 years ago, clearly are, but we're going to keep on keeping on with those for other reasons.
