I don't know of any survey on this (probably is since they survey any and everything) but I suspect most people now know how to pronounce Barack Obama.
BUT there is some software that does not - the new Kindle device from Amazon has text to speech built in but it doesn't know how to say his name.
I checked the text to speech ability of my mac mini and it does an good job on his name. Here's more on the CNN blog.
(hmm is Apple more liberal than Amazon? - better check the political contribution list)
Just to back up a bit - I didn't grow up on the internet or even personal computers. Have you ever seen the movie 2001 A Space Odyssey?
Well I always imagined computers to be the size of those mainframe things in that movie. As my engineering career advanced the computer size decreased as its complexity increased.
Today I easily do what I could not have imagined 40 years ago. Embed video clips of our President into my blog and watch live streaming video from most anywhere.
The White House has a collection of pictures posted on flickr.
Maybe if you grew up on the internet this is not surprising. But for one that lived when the President got his first jet aircraft (Eisenhower 1959) this is amazing.
I found this while browsing the White House blog (oh you didn't know about that either). The older fellow not looking so helpful is Vermont Governor Jim Douglas. Barack Blackberry Obama is well connected in our wired internet world. I like the openness and internet sharing of this White House but I hope they don't start twittering. That might be too distracting. They do have some work to do besides moving furniture.
Just after the election the change.gov site was launched. I really liked the interaction on that site. I mistakenly thought the Obama administration would continue to use change.gov.
The good news is that they continue to use the internet to exchange information with everyone.
Did you know the whitehouse has a youtube channel and various blogs?
