The idea of what a blog really is has changed greatly in the last few years. The debate of what defines a blog will probably continue forever among several circles, the same way many people have been debating for a long time about what constitutes a good writing for a blog. One of the things I notice on many sites is that any kind of regularly posted and updated writing is considered a blog by those sites.
Either fewer people are recognizing the difference between a commercial advertisement and a blog, or the idea of blogging has morphed into being all about regular content. Blogging used to be about personal opinions and original thought, and now we have those mixed with marketing, writing rules, product placements and advertisements. Is Spoken-for by Valerie a real blog with personal opinions and daily journals, or is the collection of Microsoft Windows Blogs what defines the concept of blogging together with others? Is it the passion for Kit Kat by Jen Ken that tells us what a blog really should be, or is it the Amazon Associates Blog that shows how blogs exist to help you and me make money?
