Answer boards

i have used answer boards as a starting spot to find information. however i always try to confirm the answers from more reputable sources. i do like the fact that it is quick easy way to exchange information in a non formal way eg. without the technical language. answer boards can also connect people that have similar experiences or difficulties. in a library situation i can see how it would be useful in answering reference enquires. it would also be a usefull tool to gather feedback and answer questions that are often repeated.
