Coupa, the Open Source procurement vendor, has launched their own blog! You can find it here. I'm especially looking forward to the video blogs that Coupa plans to use to explain and promote its offerings. As far as I know, this is the first blog in the Spend Management world that is being used as a replacement for other types of technical and marketing vendor collateral. I know Coupa is hoping to attract middle market customers directly and through channels, and I suspect this type of blog will be most likely to capture the attention and readership of procurement technologists rather than sourcing or process types -- which is the perfect audience for an Open Source technology. Keep it up guys -- you're pioneering something here!
