This is kind of what I'm talking about...

• It showed that I had 3 notifications
• It showed that I had 2 notifications in messenger, so I clicked on messenger.
  • I actually only had one, which was a message from Andrew.
  • Once I checked the message from Andrew, it still says that I have 3 notifications.
  • So I clicked on my profile pic again and waited to see if it went away.
  • This is the screen shot you see above.
• I then clicked on the word "notifications", it says 1.
• That's when all the notifications went away.

My point here is that when you're buzzing through the site, sometimes the notifications get hung up or don't go away and start getting confusing.
Also, another point I'd like to make is that I'm not ever sure which notification (on the notification page) I've seen or haven't seen.

I know facebook uses a light blue color for unseen notifications and then once clicked, it makes it white.

Example:

I know this is a lot...but from a user standpoint these are small things that make a big difference in the user's experience...
