I use it all the time. I work as a payroll specialist in real life, but a "genie" in real life. I am doing a full genealogy of the descendants of Timothy Bush and Deborah House, the earliest Pres. Bush ancestors. I am amazed what people were also descendants...NASCAR racer Kip Stockwell is a direct descendant of Timothy Bush Sr.'s son Fairbanks Bush...LOL...genealogy won't save the world but it will at least properly document it. ;-)
If I weren't insufferably lazy, I'd probably be doing genealogy instead of spending most of my free time on the web. I don't even drink coffee.
Anyway, it is a fun and interesting hobby, particularly as a branch of history (which is my real hobby).
