Traditional weg pages vs. blogs

What are the benefits of web pages vs. blogs? This is my first experience with blogging, but it seems to be a more immediate medium. I fling my thoughts into cyberspace where others can instantly connect and comment on them. I don't yet know what the benefits are. Do most bloggers find their followers helpful? I've peeked in on blog sites in the past, and most people who post seem genuinely helpful. I am looking forward to this aspect. I do love the idea of finding experts and seasoned users who can help me through pitfalls and tech. troubles. I'm much more comfortable using a web site to communicate, and like the fact that is is static. Once things are posted, I can use them as a reference for future use. A downside is that there isn't really interactive communication, it is a one way conversation. How do teachers use their websites or blogs in an educational setting with elementary-age students? Let me know.
