I think it's still pretty new, but I wanted to let people know about Pico. Basically Ameba made an English version of Pigg and turned it into a Facebook app. It may help answer some questions you have with Pigg. You can check it out here: http://apps.facebook.com/amebapico/
update: Or you can try it facebook free at http://pico.ameba.net Thanks to everyone who found the free standing url!
another update: it seems like the pico clock is on GMT. So for the USA eastern time zone people, the new day starts at 7pm.
