Vanguard has made some progress. But there are many hurdles. For example, regulations require that they be able to save and archive all messages in a non-rewriteable format. They had been doing that for email, and they needed to come up with a way to do that with IM messages, and blogs and wikis too. The company has also set up a number of internal collaboration sites and assigned a manager for each of the sites to regularly be checking the content posted to ensure the compliance of the information being exchanged.
