Here's an insightful quotation from the Wired Blogs.
"Blogging is not about making friends, it’s about expressing yourself truthfully and in the process providing some hitherto unforeseen insight into an important issue or topic of the day. If you make friends, that's a bonus. Real blogging is about shedding the politics and letting it all hang out. Sometimes that honesty yields less than enjoyable results, but other times the honesty of certain blog posts can inspire us all into action or thinking about important issues in a different light."
