This is the presentation for my students at Colorado Free University. I went item by item through all the LinkedIn headers plus challenged them to create their LinkedIn profile by a certain date. If you've been putting off completing your profile, you can download a PDF file and take the LinkedIn 100% complete profile challenge: Download Challenge to LinkedIn.
In spite of its clunky interface, credible business people can no longer afford to avoid LinkedIn.For all the continual media frenzy over Facebook and Twitter, the most
remarkable social networking story of all may well be LinkedIn,
the global social network for business professionals founded by serial
Silicon Valley entrepreneur Reid Hoffman in December 2002.
Last week, a bullish LinkedIn CEO Jeff Weiner announced its 50 millionth member, stressing that while it took sixteen months for the social network to get its first million members, the most recent million only took 12 days. While the LinkedIn 50 million may pale in comparison with the Facebook 300 million army, its achievement is quite remarkable when one considers that there are only around 360 million white collar professional people in the entire world (at least according to the latest International Department of Labor numbers).
So over 10% of the world’s professionals are already on LinkedIn. And with the social network now signing up a new member every second of every hour of every day, it shouldn’t be too long before the other 90% of the world’s business professionals eventually wind up in the LinkedIn universe.
