OK, back from Recife, photos soon,
Meanwhile, back to work tomorrow. :-(
And, as part of the very slow, incremental upgrade of my online life, there's a new OPTIMAES blog, the aim of which is to replace the OPTIMAES wiki as the main place to talk about OPTIMAES. (Despite the overall wonderfulness of wiki, blogs seem to be better at holding a conversation.) I'll also do more of my general writing about alt.money there. Previously I did it on Tribe, but that now seems to be hidden from non-members.
