I check my email multiple times a day. Often enough that rarely, and I do mean rarely, do I have more than 5 or so unread emails sitting in my Inbox waiting for my attention. (Except for mornings, of course, when I might have 30 or more that have congregated overnight, waiting to ambush me.)
So imagine my surprise a few minutes ago when I opened my email to find 17 new emails. I had just finished reading everything a mere 10 minutes earlier.
The mystery was solved as soon as I noticed that the majority were notifications from Facebook. Somebody has been very busy posting, tagging, and commenting!
