Use of Web 2.0 technologies

I have been interested to follow the postings on NZ Libs re the use of Web 2.0 technologies. I thought Brian Flaherty made some interesting points. It is easy to get carried away with all the possibilities of a particular technology and forget how much time it is going to take. Even in my personal life I find it hard to keep up with reading all my feeds, visiting my favourite forum, updating my blogs and entering the books I read on LibraryThing. At work I have websites to monitor, a blog to write and a wiki to contribute to. So far I have been able to resist Twitter and Second Life. Brian's thought tie in nicely with those in Data Smog. However, I think it is important for libraries to selectively use some of the new technologies in order to connect with the digital native generation. If we continue to only do what we have always done we risk being seen as irrelevant.
