What is a blog if it is not a place for freedom of expression and a way to place information so others can gain some modicum of intelligence fron the printed word?!?!

Any website can benefit from having a blog of some type.  Yes, they cost money to have on your site at first, but with one like this, you can create you own posts with whatever information you wish and then creat more and more posts as well as delete a few and edit what you have written before.  You can optionally allow others to create and edit post on your blog if you wish.

This is one of the lesser expensive ones, taking only about 4 hours to completely install, set up and for training. There are others I do use that could cost you an arm and 2 legs plus a very steep learning curve.
