From our Show Tracker tv blog:

Octavia Nasr, CNN’s senior editor of Mideast affairs, lost her post Wednesday amid mounting criticism of a message she posted on Twitter expressing sadness at the death of a Lebanese cleric who once was an influential spiritual leader of the Shiite militant group Hezbollah.

Nasr, who had worked for the cable news network for two decades, had already apologized in a blog post on CNN.com for “an error in judgment” in writing that Ayatollah Mohammad Hussein Fadlallah was “one of Hezbollah’s giants I respect a lot” after his death Sunday.

Just one more warning that as amazing and informative and as delightful as the Internet is, and blogging, and tweeting can be

it can end your job. quickly. swiftly. just ask Dooce, and now ask Ms. Nasr.

so whats the lessson? think twice before you tweet, especially if its in relation to your gig.

as they used to say at the beginning of Hill Street Blues – be careful out there.
