And what did you expect, exactly? Did you notice the name of this forum? Now, let me get this straight. You come out of nowhere, with no history to judge you by, no reputation. You introduce yourself by making a claim that is guaranteed to spark a negative response. I do not know your pet device. For all I know, you may well be right. All I ask you to do is change your attitude slightly for a better chance to get your point across.
"Useless" is a relative term. I have never used and will never use Facebook. It is totally useless for me. But I've heard it is quite popular.
