Hans De Keulenaer commented on Integrating RSS Into Your Web Site (NLA/NEMA 2008) Excellent overview, as well as good segmentation of rss tools. Many of the tools however have meanwhile disappeared for lack of monetisation. So care before investing time in any of these is needed. Thanks for pulling this together! 3 weeks ago
Hans De Keulenaer commented on The Global Energy Network The per capita residential energy use is indeed around 2,000 kWh per person per year. However, as we also use electricity in offices, industry, etc, the actual use per person is about 3-4 times larger. Hence 2000 kWh is sufficient to light homes and power appliances, but insufficient to build an industrial or technological society. 11 months ago
Hans De Keulenaer commented on 8efficiency Is efficiency always a percentage? Couldn’t we see mpg, kWh/m2 or lumens/Watt as measures of efficiency? 2 years ago
Hans De Keulenaer commented on Startup Metrics for Pirates (Foo Camp 2008) Good point. Moreover, can one measure without influencing users? 2 years ago
Hans De Keulenaer commented on Startup Metrics for Pirates (Foo Camp 2008) It depends. If your sponsor pays you 250,000 $ for running the website, 1,000 subscribers at 10 $/monthly is a pretty bad investment. 2 years ago
Hans De Keulenaer commented on Free Learning Absolutely unbelievable. But the inclination within the academic world to close doors and build ivory towers remains often strong. 2 years ago
Hans De Keulenaer commented on Education 3.0: Why should Africa Care? Let’s wait and see. How about immigration? 2 years ago
Hans De Keulenaer commented on Aaaa Powerpoint Timesaver 2005 310105 Thanks for your very generous sharing. This couldn’t come at a better time. 2 years ago
Hans De Keulenaer commented on Using a Free Blogging Service vs. Blogging on Your Own Hosted Site Isn’t the bulk of blogging time spent on actually researching and writing content. The time for used for design, learning html and using widgets/plugins is a one-off investment that’s going to be a fraction of the total cost of running a blog for a prolonged period. 2 years ago
Hans De Keulenaer commented on Brain Rules for Presenters I like the concept, but observe as well that it takes 131 slides for introducing a relatively simple idea. What if you need to convey the resonance behaviour of lanthanium-fluoride crystals? 2 years ago
Hans De Keulenaer commented on Marketing3 Presentation Excellent presentation. But just as I was starting to think the line between business and consumer marketing is fading, you drive a deep wedge between them. 3 years ago
Hans De Keulenaer commented on Marketing3 Presentation Love your association of branding with integrity. The best definition of a brand I’ve encountered so far: ’brands are promises’. Definitely belongs to the marketers bushido. 3 years ago
