I think we can all agree that technology is a fast moving target. Just when you think you know a lot, you find out how little you know. At least that's how I've felt over the past couple of years.
I've always considered myself a pretty techno-savvy professional (actually a "non-tech" geek and proud of it!) And it wasn't until I attempted to develop my own app (The 1% Edge Portable Coach) and promote mobile and social learning that I began to learn how little about technology I really knew; like, for example, there are lots of different Android platforms. It's not just Google vs. Apple.
The effort to create learning resources for clients in the employee learning and development space helped me realize that I was plopped squarely in my own technology gap. This was frightening to me as I am a firm believer that functional knowledge of technology is a general professional competency, let alone a competency for L&D professionals.
Not only is it a competency, but an imperative for personal/life success. Consider the description and commentary by Tim Mazur of Santa Clara University regarding information and the technology gap between rich and poor.
