Gmail autosuggestDouble-check the "To" field in the next email you send, if you're a Gmail user.
Google's mail service seems to have a bug in its auto-suggest feature that is causing a bunch of people to send messages to the wrong contacts. In lieu of auto-completing to the most-used contact when people start typing a name in to the "To" field, it appears to be prioritizing contacts that they communicate with less often. 

New York City venture capitalist Fred Wilson posted about the issue, writing that they got a bunch of emails yesterday that were clearly not meant for him, but people are complaining about it all over Twitter, .
The bug doesn't appear to be affecting all users (I haven't noticed anything comic, for example), but it is definitely not an isolated issue, based on the Twitter response.
