Over at Ross Mayfield’s blog there is a great post including a podcast interview with three people that are heavily involved with cutting edge Internet technologies. In particular it talks about the excitement surrounding Wikis, Weblogs and RSS and how they are impacting business.
In particular I appreciated the point in this interview that while the technology behind these initiatives is not that revolutionary, it’s the changing perceptions and they way users are utlising the technologies that is having the impact and creating excitement. Blogs and Wikis certainly are not complicated tools, but the mainstream adoption and powerful ways they are allowing people to collaborate together (think wikipedia) are fueling the revolution.
See if you can spot the academic in the interview 
I think there is real scope for collaborative tools such as wiki – but my own experience of hosting one for travel revealed that like forums – getting a community of contributors together can be challenging. Also, this wiki became the target of spammers – so eventually I had to shut it down.
