The Internal Memos site is billed as ‘the internet’s largest collection of corporate memos and internal communication’.
It also could be called ‘a site for the most bored and nosy people on earth’. (although the current memo about holiday dinner parties from Martha Stewart to her employees does make for rather funny reading in light of present…er…revelations).
You’ll need to subscribe to read some of the more juicy memos though, which makes me think that the site may be skating on very thin legal ground.
