We're starting a new blog over here at biz.advanceitmn.org. The focus will be open source Web Content Management Systems with a lot of focus on Drupal.
In this blog we'll spend some time on comparing some of pluses and minuses of open source and proprietary systems (and whether this is even a good question in the first place). We'll look at how some of the commonly used open source Web Content Management System stack up. Then we will spend considerable time on Drupal showing its strengths and some of is weaknesses.
