Slamming the boards

There is an answer board for librarians at wetpaint.com. For the Brisbane Square library I think a library blog - interactive if possible - would be best for providing information on events and services with videos and pictures enriching the content.
An answer board would be great as a feedback post where customers could feed comments and have them answered by librarians. Vodcasts and podcasts have huge potential to enliven our library website and promote and report on events, programmes and services.
