Hello, I'm a freelancer ready to answer your questionnaire for 10USD for each submission. Filter bubble is a topic I can offer you good authentic responses, since I use social medias daily. I'm pasting the last question from the questionnaire here, which is; "Do you have any other comments related to filter bubbles?". This is my response, "From what I know this term originated in 2010, and from what is said the whole thing looks bad, especially for democracy. I need to read more on it to give you the most honest and well thought responses." Thus, I'm your guy, just give me a shoot. Kind regards, Stephane.
