This is a great example of how to utterly destroy yourself with social media.
What we see here is a guy who, apparently, wants to be your (the plural your) personal brand strategist. Insodoing, he has spammed everyone he knows at Twitter, not realizing that everyone who follows him sees his spam fly by in real-time.
The delivery of your message is key. In this case, Hajj Flemings' message was that he was there to help people with branding strategy.
The medium he chose (Twitter) was apparently one he didn't know well. Twitter, being a broadcast medium, broadcast a series of identical messages everyone subscribed to Hajj's feed.
While the specifics of this are interesting - more important here is the understanding that the Medium may not be the message, but it sure influences they formulation of the message.
When any business steps foot into the social media sphere, they need to understand the mechanisms being used and the structure of the community behind them. I'm sure more than one person stopped reading Hajj's post after his spamfest today.
