Interesting... I recently signed up for the Blog Meetup that's happening all over the world today/tomorrow and discovered a few fellow bloggers here in Madrid.
Uma B. is a Spanish/Irish writer living here in Madrid.
Alberto Muï¿½oz writes El Bloque, it's in Spanish (which of course makes sense...)
And so is Olalla Cernuda's... but it doesn't look like she's updated it recently.
Addendum: It's been cancelled because there weren't enough people. Oh well... I probably wasn't going to make it anyways... ;-0
