Business Insider has republished an (edited) version of an Introduction to Bitcoin talk I gave to a professional conference last year. You can find the original, unedited version on Slideshare.net.
The comments thread is particularly interesting, and I have responded to a number of them, attempting to address a the common concerns, questions, and misinformation people have about Bitcoin.

I can’t respond to everything, but I do read everything!
