Even More questions about Blackboard

Just realized that my son's second grade class has access to Blackboard, and so do the fifth graders (where homework assignments from the teacher are supposed to be posted). They use Blackboard in the Middle School, and it is used in the High School (where students can post and submit assignments). And we are supposed to use it on the college level. Now, someone please tell me, how this BB CMS is appropriate across all of these educational levels; is it that brilliantly-designed with so many options that can be tailored to the individual learning needs of vastly different audiences? Hardly!
