Bauerlein is a naysayer in a yes but since  the idea is that the digital age is great for sharing information but he is claiming that the wrong information is being shared such as parties and social events instead of scholarly links. 

Here from the very beginning, Pamela is a naysayer. She introduces the fact that people seem to believe that others want to know what is going on in their lives. Social media, or even communication itself is full of information that she and I wouldn't want to hear. Pamela implies that people do think that people care and this is to say that people don't care or need to know about everything going on in their lives. 

Colby Hall is a naysayer in this part of the article but in a yes but sense. She states that the people she knows in Kansas are dear sweet people but sees them depressed when she gets a notification on facebook. This is saying that she likes the way we are all connected through social media and have the power to just use a click send to stay connected but the send button is being misused at too much unnecessary information is being sent such as farmville requests. I know I get annoyed when a notification is just a request to cut my neighbors grass. She is naysaying about how we need to share even the smallest changes in our lives as though people care.
