As reported last week in the ComputerWorldUK article, Major corporations post sensitive data on Google calendar it appears that you can tell two friends and they can tell two friends, and so on and so on.
Or, you can just make the entry public in your Google Calendar and the whole world can know.
Again I wonder how much information we're giving Google, exactly.
Or how much information we're giving our competitor's via Google.
And Google's defense is "well, just don't make it public". Except the default setting makes it public, the settings being Default, Public and Private.
Dear Google: Set the default to private and prompt to release to "public" that would be the not evil thing to do. It's not rocket science.
Have a good one.
