Wiki, Wiki, it is fun. and it is useful

It seems the Wikipedia be coming the first source for the librarian answering the general referecne question now. At least I used it a lot. Wiki is fun and useful. It si fun because it is easy to use, it is useful because is carrys a lot of reference inforamtion. Some wiki are well organized but some are not. teh free entry and the flexibility are the best benefit. But too open is its cons. But I think more and more perple will like it because its functions and context.
