Even though it's Thanksgiving in the United States tomorrow, Spend Matters is not going dark. For the rest of this week, we'll continue to bring you news and analysis. Be sure to check back both Thursday and Friday for thoughts and commentary on all things Spend Management. But to make sure that all voices are heard -- not to mention giving ourselves a bit of a break -- we've asked our blogging friends from 2Sustain and @Risk to contribute two columns on Friday, offering their market outlook for 2010 in the areas of sustainability and supply risk. If you have not had the chance to check out either site, I would strongly encourage you do so. While both sites are authored by Aravo employees, they are completely vendor agnostic. They're expert, conversational and worth a read everyday.
