Traditional web page versus blogs

What is the difference between traditional web pages and blogs? For starters, blogs are so much easier to access and comment on. In this class, I can truly see the need for this. If I have just hit a road block on things I am working on, I can post it. My teacher can comment on this roadblock and tell me how to break it down. Now only will this help me, but every other student in the class and anyone else reading this blog can bypass this roadblock as well. In the traditional web page, I would write about my problem only. My teacher would read it. She would then have to email me how to solve the problem. This would cause you to leave the blogging website and go to your email account. This is very time consuming.
