Thing #7 WIKIs

I have a family WIKI which I started. It is nice but my family finds it too much of a bother. They are not Techie people. My nieces and nephews send me pics of their kids when they want and see no real reason to use a WIKI. I would think that if you had a special interet you could either start one for that specialty or join one. I find it had to find the time to continue to follow things like this.
