Why simply have a web site when you can have a centralized communication center? Much attention has been focused on the lively debate over whether weblogs are good for attorneys or not, and without revisting that topic in depth, let me say that I believe an appropriate content management system, whether you call it a weblog or not, is a great communications tool for any law firm.
I personally use pMachine Pro. I find it to be an extraordinarily efficient way to serve up content, communicate with my community, and to be found in the search engines more effectively than I have seen with my static page sites. However, I may have to revisit this issue based on an announcement made yesterday by the makers of pMachine Pro.
