wiki and beyond

i love the idea of wikis. you hear about them and may use them but to actually be actively involved in a conversation, especially planning a holiday, would be great. i can benefits such as book clubs doing a virtual book discussion with other book club members who have read the same book, connecting with youth to find out their wants, needs or desires for a library environment, groups of people getting together to discuss same interests or sharing skills/knowledge....endless really especially outside the library environment. but with most things time constraints would be the only casualty for me to become actively involved to pursue for personal reasons, much to my dismay....
