The layoffs at AOL we warned about did indeed happen yesterday, according to Kara Swisher of Boomtown. 300 employees at the Time Warner online (TWX) division were said to have been pink-slipped at a “mandatory HR meeting” yesterday.

A commenter on the Post I.T. blog who says her husband worked for AOL wrote, “he was given 2 months severance and 2 months free COBRA. He worked for AOL for 15 years.”

Another commenter confirms that Bebo employees were also laid off: “AOL shut down the entire Austin Tx Bebo office today. … We were also given 2 months severance and 1 hour to vacate the premises. Nice.”

If this isn’t sad, we don’t know what is.
