‘Another Google Privacy Flaw – Calendar Unexpectedly Leaks Private Information (Disclosed)’

Interesting discovery from Terence Eden (which Google now says is not a flaw). Basically if you add a appointment with an email address in the appointment title — the person with that email address *may*, or *may not* get an invite. Even if you specifically are trying to not invite them.

Good lord — the inconstancy of the “feature” alone is enough to drive you nuts.
