The spirit of our times... Trying to answer the question about what's next?
The answer is important because it impacts markets, businesses and your websites.
For example, the 2008 USA Year-End Google Zeitgeist shows that the fastest growing terms in search are obama, facebook, att, and iphone. So, how does this help you with keywords research? It can help you to take advantage of trends in your markets. If you can somehow tie your products to the major trends, then you can take advantage of huge amounts of traffic.
All this noise about blogging in PR/marketing is missing the bigger picture - blogging internally. Our grandparents had Laurel and Hardy, Gapingvoid, Hugh - "Blog bashing doesn't phase me too much- I actually find it rather entertaining. What can I say? It's rather fun watching people being wrong, again and again, for the same "I have a dumb ass suit & tie job in a big company ergo I must be terribly important" reasons."
