Did you know that Element K is now on Twitter? We started using Twitter as an organization in late June, and you can follow us via the account “Element_K,” which can be found at http://www.twitter.com/Element_K. Through this account we are sharing links to interesting industry articles, blog postings, resources and more, as well as announcements about Element K webinars and other happenings.
Beyond that news, back in February I wrote a posting here at Element K Blog—“Twitter, Twitter, Tweet, Tweet”—intended to help people in the L&D industry get started with Twitter. Since then, of course, Twitter has exploded in popularity, brought on in part by celebrity and media attention, but also by very legitimate uses of Twitter, ranging from its role in political events, to its corporate use for marketing, customer service, and even sales, to its use by everyday working professionals as a powerful information gathering tool. It’s this last use-case that I still think is important for learning and development professionals to take seriously.
With that in mind, and because it comes up at every industry event I participate in, I wanted to provide another posting on this topic. Refer back to my earlier posting for a basic introduction and valuable links for more information—there are many more I could share that have come along since, but you only need so many “Twitter for newbies” articles to get you started.
More importantly, I wanted to provide an updated list of leaders in the L&D field that you might consider “following” on Twitter (most, but not all of whom, use Twitter regularly). For each, simply visit http://www.twitter.com/username, such as http://www.twitter.com/Element_K:

No doubt I am missing several key people, but this is a good list to get you started (Not seeing someone you are looking for? Try the much larger directory of people in the L&D field who are using Twitter provided by Jane Hart’s excellent Connexions Directory.)
