I highly recommend every Debbie Weil has to say. I've been following her through her WordBiz newsletter and found it very useful in improving my marketing copywriting. Your company should be seriously considering the use of weblogs for internal knowledge management.
Blogging serves as a useful way to discuss abstract information while capturing the thoughts in writing. It provides individuals a way to express their views on individual topics without direct real-time conversations. If your people are busy, blogging can help them stay in touch without the risk of losing information laden email messages.
How to use make weblogs useful for internal discussions...
Provide the tools. Two software packages I recommend (both very moderately priced) are "Radio Userland" and MovableType. Both allow multiple users, and both are very flexible. You should be testing this concept with one of these tools today.
Categorize by function unit. Build discussion categories around topics that make sense for your company. This can be as simple as naming projects per functional work group, or open as topical channels.
Encourage participation. A few minutes a day reading other peoples project comments, and sharing your own can grow your companies knowledge base around a certain topic. Since employees can do this anytime they want, it makes it easier to put all your experts together.
Utilize news aggregation. Blogging tools like "Radio Userland" have built in news aggregation tools that let you see headlines from other blogs in a simple easy to follow format. This facilitates the level of communications and commenting on each others work.
Integrate into website. Use a flexible interface like Netscapes My.Netscape to let employees customize their intranet home page, let them display the headlines relevant to their job. Dashboard tools are available, and XML is simple to integrate into most web servers via CGI.
Use communications guidelines. Make it clear what can and can't be said on a web logs, for internal systems this really isn't much of a problem. If you ever plan to share weblogs with other companies (very valuable) you want to at least be consistent.
Improve individual skills. This doesn't mean a creative writing class, but each employee must have a certain proficiency in written communications. Choose tools with spell checkers, and when one isn't available use a dictionary.
