What is a 21ster?
A twenty-firster is someone who (regardless of their age) loves technology and wants to use it in genealogy research. Generally speaking, they can't imagine doing research the old-fashioned way without first exhausting all online repositories. They are usually busy people with busy lives. Utilizing technology allows them to get more done faster. They shop online, bank online, talk online (e.g. Skype, Google+), and socialize online (e.g. Twitter, Facebook). It just makes sense to them to do research online too.
