I was reminded recently about how slowly change occurs. My parents, who have been retired for awhile now and get most of their news from the corporate news media, are not sure what a blog is. The same goes for Twitter, Facebook, Google+, and many other platforms. When we think about the massive impact the Internet has had on atheism, religion, and our culture more generally, we would do well to remember that there are still plenty of people out there who haven't been reached by the full extent of what the Internet has to offer. We have only just began to tap the potential.
The good news is that we can expect this to change dramatically in only another generation or two. While my parents may not know what a blog is, I certainly know. And I'd estimate that more than half of my same-age peers know. But still, I work with plenty of people in my age group (and some who are quite a bit younger) who aren't sure about Twitter or Google+. This probably will not be true of their children.
I bring this up to point out that you and I are engaged in something that is still fairly new. Others are going to take some time to catch up. As I struggle with my own impatience, I will try to remember that. The trend is moving in the right direction, and far more people will be reached in the future.
