blogsphere vs. mainstream media

The last decade of the 20th century will be remembered by the global Internet and the first decade of the 21st century will be remembered by blogs.
Blogging is the most popular and sophisticated way to express your own oppinion on a public published articles, theme conversations, topic comments, etc. Blog is a replacement for the mainstream media. In oppinion of several critics, bloggers have no checka and balances. There's a lack of control in that media sphere.

Blogs do not represent a higher standard of media integrity and they have their advantages and disadvantages; blogs are products of people who may or may not know what they are talking about but on the other hand, they are useful because they are interactive, immediate and accessible to anyone who stumbles on a truth the mainstream media, for whatever reason, to ignore. They deliver unique values, publication and distribution costs "nothing", etc.

Overall, I believe that they are quite useful and they are not the substitut for other traditional media, blogs won't even replace them, but they will complement them. They aren't better than traditional media, they are just different.

I assume that that extracts some additional value from the mainstream media and they provide immediate feedback to those who use them.
