Blogging About Blogs

I've never been big on blogs. They are usually something I just happen to stumble on while trying to search things on the web.
Blogging is a great way for people who share a common interest to state their opinions and share their views about a particular topic. Blogging is becoming such a huge trend, which makes it a perfect vehicle for advertising.
People can become very dedicated to a particular blog, constantly keeping up to date on new postings. The author of that blog now has the full attention of its readers. What better way to have your product get noticed then having a blogger write good things about it. Word of mouth is key in getting your product notice. This could also have a reverse effect though. If a blogger had a bad experience with a product/service, that could really bring a business down.
I think blogging is great, as long as advertisers don't start taking advantage of impressionable consumers. If a business is paying a blogger to glorify their product, I'd want to know.
