I admire Oprah from both a brand and marketing perspective - she is the utimate in creation of self-brand with little or no assistance from the industry in which she dominates.  She made herself, period.

Which is why her last night's status update on Twitter asking for people to tune into her network (noting "especially" if they have a Nielsen box) was rather odd and embarassing from a PR perspective.

My takes?  

First, I am glad the status update was deleted (thank goodness) and we know the status was not a hack since it became @-replied to and  mentioned after and referenced by Oprah herself.  Second, I am upset that the OWN network did not take off as it should have .  Third, there are many poistive new things that Oprah's team can do to get that amplification for what they need - which is eyes on the channel.  That, however, would be a few pages of a proposal.

This status update, though, was not very Oprah-ish.  Good move to delete, and it sounds like she needs to shake up her marketing team.
