As a counter-example, I tried to be brief as well in another post on there (http://danieltenner.com/posts/0003-impossible-is-a-step.html) and that one didn't work out very well - when I asked people why they didn't like it, they said it was too short and lacked substance/examples.

I'm a big fan of keeping things as brief as possible, but from what I can tell it's not the best format for the web. I've only seen it work for people who have huge followings already (e.g. seth godin). Even there, most of their posts don't take off...

I could be wrong of course! Good luck to both of us :-)
