There's no secret information here, just a small degree of uncertainty about the creation dates (and even founders, in some cases) due to database changes in the early days. Birthdays could be in November, December or January, but I didn't want to miss the chance to honor these communities. Moving into 2005 there's much more clarity on founding dates.
