This is a plug for the Brevard BioDiesel Blog.
I was thinking about updating my broken Google Maps biodiesel stations mashup, but balked since someone over at Brevard created a much more complete map! It includes stations all over the United States using data from biodiesel.org.
A cursory perusal of their blog yielded interesting posts on Honda plans for selling new diesels (instead of hybrids) and problems/FUD regarding palm oil.
