Organizations wouldn't consider for a moment the concept of not knowing where their financial accounts are (or not having signatory power over them). Ditto accounts with key vendors and suppliers.

Yet my colleague Jeremiah Owyang found in the course of conducting research for his just-published report, "Managing Social Media Proliferation," that companies have, on average, 178 social media accounts (not counting employee accounts), yet the majority don't even have an accurate inventory of these assets.

This is a must-read for any company active in social media. Jeremiah and his research team also evaluate 25 vendors in the space. So this is also a buyers guide (a first for Altimeter Group research).

Take a look, and please feel free to download the report or share it with colleagues.
