Do you think we have too much fragmented or misinformation in our lives due to media over availiblity? READ?

I use the computer much more than I used to and learn a lot on line. I remember, I once would be talking about things I read, or heard and could recall & shared in conversation the source of my information for validation. Now, I read a little here and there online, read 1/2 an article in a waiting room, hear a little news & find myself not remembering my sources. I hate saying, "I read this somewhere....", and not remembering where. I think we share misinformation this way without meaning to. We should always consider our sources, ya know?? This bothers me. I worked in a library and know folks do want to know the source of information. Sometimes I will say, "Google it. There is a lot of information supporting that thought...". Makes me feel bad.
