Getting the Most Out of 21st Century Tech Blog

November 25, 2013 – It was November of 2009 when I started this blog focused on understanding where we had come from technologically and where we were going here in the 21st century. Now 658 blog entries later I sit back and look at what the sum total of all that I and much appreciated guest bloggers have produced and am somewhat amazed by the totality of it all. More than 450,000 words appear here organized around a range of topics starting with agriculture and ending with world population. By the numbers and subject area here are some of the more popular postings:

• 236 articles on the environment of which 135 focus on climate change science.
• 209 articles covering energy, 59 of those on solar, 34 on storage technology, 30 on wind, and 60 discussing fossil fuels.
• 143 postings devoted to medical science and technology.
• 131 articles looking at outer space from the legacy of the 20th century to what lies ahead both in human and robotic space presence.
• 105 articles dedicated to transportation technology.
• 101 postings on land use, mining and 68 specifically on agriculture.
• 93 articles on robotics.
• 85 postings on industrial technology other than robotics including articles on manufacturing and materials science.
• 61 postings dedicated to the subject of our growing world population and the challenges we face.
• 60 postings about computers with 29 specifically focused on the present and future of artificial intelligence.
• 60 postings on the world’s cities and the increasing rural to urban migration that characterizes this century.
• 52 articles covering communications from the 19th century invention of the telephone to today’s and tomorrow’s Internetworked world.
• 51 postings dealing with the state of our oceans and their future.
• 50 articles looking at how politics, politicians and governments are dealing with technological innovation and what lies ahead.

In terms of reader comments the most come when I post articles on energy and space. Cold fusion pieces have drawn lots of commentary, in fact, the most of any.

Early on I began to post links to this blog on social media sites. My Facebook 21st Century Tech page is increasingly getting visitors who may not subscribe to the blog site itself. On LinkedIn a growing number of readers have gotten involved in many lively debates running to hundreds of comments per posting. Many of my postings appear on the blog pages of The Futurist, the e-zine of The World Future Society, one of the most visited sites on the web devoted to speculating on our future. Readership continues to climb as do subscriptions to this blog site. For this I am eternally grateful.

If you are a first time visitor to the site I hope you take advantage of the many features that allow you to mine it for the information here. You can review archives by category using the pick list available on the right side of the home page. You can use the file tabs to select specific topics and then look at the collection of articles. You can click on the magnifying glass next to the file tabs and type a key word or phrase to find information you seek. And you can check out the Tweets listing which covers more than just the blog postings including my entries on Twitter for subjects on technology and the future that have interested me but that I have not necessarily written about.

To all of you I thank you for your visits and your contributions. I expect to be at this task for many years to come and welcome you to continue to come along for the ride.
