All this is to say that I'm not trying to claim a title of first geology blog. I'd just like to hear from other geology bloggers from the Paleozoic era of blogging, before mid-2003. Maybe someone already knows who had the first geology blog.
People were talking about geology online long before the Web, in listservs and on Usenet as well as on for-pay sites like the Well and Compuserve (those were the original "ask-a-geologist" sites). And from the beginning of my time at About.com, in 1997, I was encouraging geologists to get online and tell the public what they were doing. Many of them, notably teachers and grad students on their college faculty pages, were doing that long before blogging. Blog software just made it easy for anyone to post essays and get into organized conversations about them. Call blogware the innovation that sparked the "Cambrian explosion" of geological online discourse. Today I feel us creeping into the Ordovician, whatever that may be.
