"The hashtag #DeleteFacebook appeared more than 10,000 times on Twitter within a two-hour period on Wednesday, according to the analytics service ExportTweet. On Tuesday, it was mentioned 40,398 times, according to the analytics service Digimind."
Is this really such a big deal for Facebook?
Suppose 50000 persons delete their Facebook everyday, then it will just lose 1,825,0000 users one year, not counting new users joining Facebook every year. And Facebook has 2 billion users.
Edit: The number lost in one year is 1,825,0000, not 1,825,000.
