The Point of Blogging?

When I decided to make my way into the world of blogging I thought, "wow, the possibilities of blogs are endless, people of every race, religion, creed, and culture sharing their ideas and advancing the understanding of all those who read and participate." Well, I apparently was wrong. The most popular blogs are not those of philosophy, literature, science, or anything that actually assists in the acquisition of understanding. Instead petty pop culture pollutes the brains of the people involved in blogging. Why should we care about people who do their jobs, just like the rest of us? Actors and actresses do preform a legitimate service, entertaining us all, but don't they deserve to go home at the end of the day, and be done with work? Why must we make their lives the focus of ours? It seems silly to me to want to know what color a certain female celebrity's panties are, or who so and so is dating now. Why do people devote hours, or even days of their lives to discuss these trivial topics? Blogs, I still believe, have a great potential to provide a place where people can converse and enrich each other's understanding, but people must want to gain that understanding first. If only bloggers cared as much about furthering the spread of understanding and beneficial ideas as much as they cared about pop culture. If this were the case bloggers would become more mighty than any military, more intellectual than the most studious professor. We would have at our disposal the combined brain power of the world to solve the problems plaguing humanity. We could shake the ground with the power of millions of unified voices.
