From this blog post, via Flickr, from the Topeka and Shawnee County Public Library 

I like this image a lot, because I think this poster conveys the most important aspects of Library 2.0, and why librarians should try to integrate these tools. It provides more ways to connect with users and gives opportunities for more services. It also can remind us that it is important to make sure library users are aware of the resources available to them at the library.

I thought that this video was interesting and relevant to our discussion in class last week. It outlines some of the pros and cons of having and maintaining a blog versus a website. It has a more commercial perspective, but that can be useful for librarians to think about as well, since it will be more focused on optimizing outputs and increasing traffic. There are also a lot of comments on the YouTube page, including one from the uploader mentioning that her own views about blogging have changed since she made the video. I definitely think that it is an interesting starting place, although certainly not an answer to the question of which is better.
