The cross-disciplinary open access journal PLoS One launched this week, and already has quite a few interesting articles.
The best thing about it is that all PLoS One articles are Creative Commons (Attribution)-licensed, and are published in a standard XML format: the NLM's Journal Publishing DTD. This means that anyone can make use of the articles in any way as long as they provide attribution.
So: PLoS Too, an automatically updated mirror of PLoS One and a testing ground for trying out article display formats.
Update: Added auto-tagging of articles; could do more, but the PLoS One RSS feed is broken.

very cool - good to see PLOS getting off the ground, too.
I looked at the source to see if you were adding any microformat-like css classes to the citations of the articles, and it looks like you are, although not to the extent that you do in hubmed. nice.
I'm curious if you are changing these along with the discussion on uf-discuss, or if you've settled on a set of classes for another reason?
Happy new year,

The citation microformats there at the moment are the ones I added early last year - as consensus is reached in the official microformat discussion I'll update them to be in line with those recommendations.
