When I was working at a law firm, I proposed the idea of using wikis for particular projects such as for example support lawyers using it as a means of research when there is a major change in the law, but also as a means of getting people known throughout the organisation as knowledge disseminators. At the time my senior manager didn't really see this and the idea was put on the back burner. It is interesting to note that in today's The Lawyer there is an article highlighting that Linklaters are going to launch an internal wiki called Linkpedia if a pilot is successful which plans to capture internal knowledge and to organise and share it better.
As I have highlighted earlier in posts, trust in one's staff is one of the ways to encourage knowledge sharing and encourages people to contribute because they now have a forum where there work will be recognised.
Kudos to Linklaters for doing this where others hold back. It will be interesting to see how this develops.
Maybe one day, law firms may also look at firms like Cogenz to deliver social book marking on the same basis as de.licious to save interesting intranet/internet pages. They could then share those bookmarks internally and use it to find experts in their own community. I think that these two technologies working in tandem could be highly useful to knowledge intensive organisations.
