"Salesforce is basically saying that its 2,000 sales reps can't get the job done and that they need to copy Yammer's model," Yammer CEO David Sacks told us. "This is like Goliath dropping his sword and armor and chasing after David with a sling-shot."
However, Sacks cautions: "Other people have tried to copy our model, but aren't showing similar growth. Salesforce may find that it's more difficult than it looks."
