When you go online, you'll find millions of people using Twitter every day. It may appear as though everyone knows what it is and how to apply it in a private or work setting. However, this is not the case "in real life" (i.e. not online or in cyberspace ;-).
If you ask any person "on the street" about Twitter, most people have not even heard the term. It's true! My questioning people has lead me to an estimation of about 6 out of 10 actually still don't know anything about Twitter. OK, so it may vary both demographically and geographically, and it certainly does. But here's my point: Even though Twitter has the fastest adoption rate online ever, most people still don't know about it and are missing out on this amazing communication tool - big time!
Yesterday I did a quick poll among some enlightened friends and contacts (just simple unvalidated questions), and even here the statistics reveal "ignorance" or great potential, to put it that way:
Among experienced every-day computer users the big majority still don't understand or use Twitter.
