I just published an article on the IBM developerWorks site called Wikis, blogs and other community tools in the enterprise. It elaborates on some of the points I made in my previous post on this subject. I tried to show that all the emerging social and community tools have a role in fostering teamwork and collaboration These new tools in some cases may replace enterprise document management based solutions, but in general will complement them and reach teams that are not adequately served currently. Wikis in particular are based on a new set of assumptions that say as much about the way people want to work as about the tools they need.
Take a look. There is much more to be learned and reported on this topic and I will be posting more as we gain more experience using all these tools in combination.
