According to a LexisNexis survey on how "information professionals are adding value to their organizations through technology" 39 % of librarians have accessed blogs and 34& have looked at wikis.
"More than nine in ten surveyed access news websites (92%), and company websites (93%) at least weekly (or more often). Video or audio podcasts were rarely accessed. Less than two in ten access video podcasts (16%), or audio podcasts (15%)."
If we want to establish ourselves as information professionals I think that it is critical for us to start not only accessing blogs and wikis but also use them on a daily basis to deliver information to our patrons.
It is also important to show library users how to get information trough blogs, readers and RSS feeds.For example at Queens Borough Public Library we are starting a new class, where customers will be able to create their own blogs, subscribe to RSS feeds, add widgets to their home page; explore podcasating and videocasting and discover new Web 2.0 sites for creating pictures, shopping, time management and a lot more.
