The wind or the sun?

The Wind and the Sun were disputing which was the stronger. Suddenly they saw a traveler coming down the road, and the Sun said: “I see a way to decide our dispute. Whichever of us can cause that traveler to take off his cloak shall be regarded as the stronger. You begin.” So the Sun retired behind a cloud, and the Wind began to blow as hard as it could upon the traveler. But the harder he blew the more closely did the traveler wrap his cloak round him, till at last the Wind had to give up in despair. Then the Sun came out and shone in all his glory upon the traveler, who soon found it too hot to walk with his cloak on. - Aesop

Many workers approach collaborative tools with skepticism,  fear, or as a burden; "something else I have to check." Others bring to the workplace their personal use bias and see them as frivolous time wasters. How are you addressing people's cloaks of resistance? Are you slowly and gently radiating the opportunities and advantages or are you just pushing hard for rapid adoption?
