If you never tried pushing down a huge number of words down your facebook status then here is a restriction you must know if you ever thought of trying it.
If you don’t know, Facebook has some restrictions for updating its Facebook status. You cannot type in more than 420 characters as an update. Thankfully this is 3 times more than Twitter’s character limit of 140 per tweet. If you try updating more than 420 characters, you will be greeted with an error.
