If you are on my orkut friends list, then you probably recently got an email from my gmail address. IGNORE THIS. Send it to the great bit bucket in the sky. I have a friend who is both a social networks researcher and wanted to check it out.
You're sitting along doing nothing in particular, and all of a sudden there's this kind of shift. Maybe the way that you hear from one ear or the other just kind of changes, and there's a tone, but it goes into the background. This isn't tinnitus. It's happened to me twice tonight. Does it have a name?
