Most barriers to entry have a few things in common- time and fear. New things are always going to take time to learn. I read that it takes 10,000 hours of doing something to become a master at it. Getting the basics takes a fraction of that, but it can still be daunting.
Fear is the most basic reaction to something new. Most of us fear change on some level. Getting out of our comfort zone can be a huge barrier to entry. Don't dismiss it.
Like many of you, I've tried to show Twitter, blogging, and various online tools to staff members at school over the years. It seldom bears fruit. The barrier to entry is usually too high to get people moving. I need to be more mindful of these barriers and do what I can help others overcome them.
I'm convinced that all of this technology stuff isn't for everyone. But like my Twitter pal, Paula, wrote- something is. To all of you plugging away at sharing tech ideas, keep at it. And I'll keep at it too.
