Somewhat in the vein of asking about links that you-all think might be good to add to the blogroll (I'll get there, honest!), I'll mention a blog that I read and isn't on the blogroll.
One such is Phil Plait's Bad Astronomy. Not that he needs the advertising, but I do read and enjoy his blog for reasons relevant to my own aims here. Namely, he regularly has articles (I'll list a few below; apparently 'dozen' should follow the 'few') that illustrate my own feeling -- that the universe is a wonderful and interesting place, and doing science is a way to embrace that wonder.
