Wikis

I have used wikipedia so many times, but never know that anyone can edit, add any information.
Wikis are good for some, watching Leelefever's video clip, planning a trip is very useful to use a wiki, instead of emailing each other, but for medical information not sure how reliable it is, although there is some staff who will freeze a topic if errors reported by readers.
SJCPL subject guides wiki is interesting, the button Talk to the library is very handy for patron, you can leave your feed back, comments, opinions etc.
Using a wiki to coordinate library program, could save a lot of staff meeting time.
Wiki is great for book clubs, staff /patron can use it to write a book review, also it is a way to promote new books.
Wiki can be used in local history, people can share your family history etc.
