I own a variety of different websites.
I run forums, blogs, NPO websites, and event/business directories.
My niche area varies, too. I cover webmaster-related topics, outdoor recreation, blogging, and even surveillance topics. I also have a community for storm spotting - in America, it's known as Skywarn, and in Canada, an organization like it is known as CanWarn.
I've been running websites since I was a teenager in the late 90s.
