I find quite a bit of the 'taking herself very seriously' in that era of Le Guin's writing. I'm awed by them, but I don't love to read two in a row.

She's not too-entirely-deep-n-serious in person though. She's a pretty cool lady! Oddly enough, for someone who manages to show so much philosophy/message in her books, she really doesn't like the Academic drive to find THE message in a story.

I really highly recommend Changing Planes, which was written in the last five years (I think), and is...well, not short stories, but a group of slightly-tied-together vignettes of very different worlds. It's got the deep ideas and a lovely touch of lightness and occasional humor.
