It seems that I have opened up the floodgate of notifications.
I have the habit of systemically going through the notifications, and then delete them after I have taken corresponding action.
If someone leaves a comment in my blog or microblog or picture, I will check his profile, and read the blog or microblog, and leave a comment.
I will consider it as an action completed, and I will delete the notification.
Even though I am quite new in Bitlanders, the number of notifications is increasing, and I do not seem to manage it well.
