By tetrapodzoology on January 20, 2009. Oh my god. Two years at ScienceBlogs have passed, and Tet Zoo has now been going for three years. It all started on January 21st 2006 when, for no good reason at all, I started a blog over at blogspot.com. Yes, Tet Zoo is three years old. Time to look back at the past year of operation. For starters, should you want to know more about Tet Zoo's origin and history of operation, read Happy first birthday Tetrapod Zoology part I and part II (both at ver 1), and Happy second birthday part I and part II. Last year, I included a 'what happened in tetrapods during 2007'. I'm not going to do the same for 2008 (not enough time), and for an 'end of year review' of my personal activity we already have the I am lazy article anyway. So, time to look back at another year of blogging. Or, to put it another way...
