I think I'm probably done with my blog (and podcast) series of Wikpedia @ 25 posts. It's been a surprising amount of work.

Einstein's theory still passes the test: weak and strong gravity objects fall the same way
AstronNL (YouTube)
Fabulous explanation of the Strong Equivalence Principle coupled with a nice bit of recent research to prove that it holds true even in extreme gravitational fields (and therefore disproving a few interesting fringe theories). It's hard science made to enjoy like pop science: yay! Plus a Hitch-Hiker's Guide to the Galaxy reference, … -
