Thanks to Twitter I discovered last night that one of my old answers got picked up this week and linked into an article on the Discovery News: What if Earth were a cube? (My article: "How would the weather on Earth be different if it were a cube?" posted in December 2002). I'm always a bit worried when this happens that my previous self (9 years ago in this case) would have made some big mistake. In this case I'll say I'm still reasonably happy with what I wrote. I like the discussion of how the ocean and the atmosphere would have to be spherical even if the Earth could somehow be a cube. I think what is missing is a discussion of the fact that the Earth is so massive that it just couldn't be a cube, although I did link to another answer explaining "Why are stars and planets round?", by the wonderful educator and Saturn expert Britt Scharringhausen (now a professor at Beloit College in Wisconsin).
It was also fun to be reminded of the diagram I drew to illustrate my post:
