Volentia is an all-veg*an Facebook, if you will. There are profiles and apps. However there are also open discussions, so it's more like a Facebook group that sprouted off into its own website. It's pretty new as of this writing: The Whois record for volentia.com says it was created on Jun. 05, 2009 and is registered thru Jun. 05, 2019.
If you're exasperated with the damn FDA food pyramid you learned in school, you're not alone. If you're on Facebook, you might want to become a fan of the vegan food pyramid page.
