    Hey I added them all!!!

    Just a tip if your interested, I noticed that your links take people off your blog. I had this same problem on my blog also but then discovered the following: by adding a small html to the link it opens up a new tab, keeping readers on your blog.

    I’ll can tell you how if your interested, chris@beaconsouthbeach.com

    Excellent list, thank you for telling us about the adopters.

    I think it makes a difference when I think about their companies.

    For example? Zappos. I’ve never purchased from them, even though I knew about them. Learned about their recent layoffs on Twitter. Saw a very human face struggling with the decision and the aftermath from @zappos.

    Now? I’ll probably buy shoes from them.

    Maybe not an ideal way for me to be making a purchasing decision, but I don’t think it’s all that abnormal.

    Great list!
    The only question I would have is what constitutes a C-level exec worth adding to the list?
    I mean, $50 and articles of incorporation filed with the Secy. of State and I’m “CEO of Company X”

    Some of these folks I already follow - but I’ve run across some “C-level” folks who I suspect were rather, er, suspect themselves.

    Still phenomenal list you have started here!

    Great list, thanks for compiling.

    I echo GeekMommy’s question though - I would like the list filtered by company size or other status indicative of their relevance. Fortune 1000? Of size X or public company?

    Thanks for this great list.

    Very interested in how technology and new media/communication tools impact organizational leadership so we created a C-level/founder/leader tweetstream called Tweeter Leader (@tweeterleader) on the Weekly Leader blog. With your list, it will be even better. Thanks.
