WHY AND WHAT IS 2.0?

This Day in History 2.0 is a vehicle for updating my original blog. I decided rather than mess with the large number of current posts in the original blog that a complete ground up rebuild was needed. I anticipate that this effort will take the better part of a year. I hope to apply techniques I have learned from my years of blogging. Readers that have linked to the old blog will not find their links disappearing.

Feel free to email with your thoughts and ideas.
