One from many
For lunch today - citibank
citibank + social media = #FAIL
twitter says that citibank has lied to the press and their customers regarding their security breach. This is an example of how a company should NOT use social media. Because the SoDOMM (acronym credit to @tomforemski) (pronounced - "sodom" as in Sodom and Gomorrah) may come back and bite them in the arse, if someone bothers to look and follow up on the social distribution of mass media.
