However, unless you were able to issue an effectively issue an SQL query across the whole web, it would be pretty hard to find this blog by searching for my real name.

Of course, an agency (such as google) could do a statistical correlation between my style of writing, topics I chose to write about, other services I log into at the same time, etc to have a high probability profile between a username and a real name. Then employees would buy the information from that agency the same way banks pay for access to your credit record.

Certainly something to keep in mind.

I see this happening in 10 years. It may not apply to your situation, you’ll probably be old by then, but many of the younger bloggers would regret it.

Trust me, many years ago, people used to think that nobody would be able to find their posts in the future. Google came along and crawled every nook and cranny of the Internet.
