I learned that the internet doesn't open up new windows that it only limits us to what it thinks we are comfortable with which was quite shocking to find out. I now feel that the internet it cutting us short and not giving us the options that could be useful. My big question toward this is why not give us more options than only giving us limited resources because isn't that what the internet is made for? Having a wide variety of websites to choose from and to look at. And im not quite sure how to improve my effectiveness of my searches maybe wording it differently.
