Many blogs are concerned with current news events and often provide unabashedly partisan commentary. "Blogging," of course, is the act of writing a blog; those who write blogs are sometimes referred to as "bloggers."

Who knows? The world may be a safer and ever more comfortable place to live?. I mean, we have seen single-interest groups - pro-choice, environmental, animal rights, and gay rights groups being the most prominent in the past centuary. Although I am always feeling since reading about the hardcore 60s that social revolution has wilted to becoming defensive battles, which seem very unlikely to create broad social change.
