While Yammer has made some enterprise traction, most companies that use it are smaller to mid-size businesses versus large enterprises. Most large enterprises with whom I’ve spoken about Yammer express trepidation over the service’s pricing and community model. At the same time, SMBs with whom I have spoken about Yammer don’t seem to have the same security or expense concerns, so Yammer could stay a viable solution for the smaller markets. The introduction of Salesforce Chatter, and the already strong SocialText solution, should knock Yammer out of enterprise consideration.
