Because you cannot carry on a conversation with a data site. You ask a question and answers come up but you cannot question any of them and get a response. What you have to do is keep Googling each question and it is not a very satisfying expenditure of time. I expect you can GOOGLE everything and thus the reason for an internet social site ceases to exist. I GOOGLE lots of things. I also ask lots of questions because I'm very interested in what people think. Now when I ask a question and I get a link to something without any conversation at all I wonder why the person didn't pause awhile to talk things over? It's helpful yes. But it is not nearly as satisfying s engaging in conversation with another human being. Well ya can't have it all. I guess.
