Who Should I Be Following?

When stated like that, "Who Should I Be Following?" doesn't sound so good. What I mean is... on Twitter, what people should I add to the list that "follow"?

I've not blogged here at Philosopher Stone about my use of Twitter. I started late last year, right about the time that apparently Twitter's growth really started to skyrocket.

I get a lot of value from Twitter, especially professionally as I follow several dozen people who are in the Learning and Development field (sometimes called "Training and Development" or other similar names). I've listed some of these people at this posting at the Element K Blog (I'm the company blogger). The list is not complete, since I've added many others from the industry since then, but that gives you a sense of it.

But what about gurus, experts, smart people, technophile geeks, etc., who are not in the L&D field? I follow some people who specialize in different areas, and I get value from them too. But I'm sure there are many interesting people that I could add, and that I'm just not aware use Twitter. Here are the folks of this type that I already follow (in no particular order):

• davewiner / Dave Winer
• LanceUlanoff / Lance Ulanoff
• rohitbhargava / Rohit Bhargava
• ginatrapani / Gina Trapani
• Lifehacker
• thurrott / Paul Thurrott
• gtdguy / David Allen
• Scobleizer / Robert Scoble
• jimmy_wales / Jimmy Wales

So... who else would you recommend? Who are your favorite people who tweet, that you think have broad appeal along the lines I just described? Please give me their name and Twitter account name in a comment to this posting. Thanks!
