OK, so my understanding of Web 2.0 is the fact that people and technology are working and collaborating together. The app, Instagram, is an example of web 2.0 technology because you take pictures and upload them to their server. Other users can view your photos, comment on them, like them and share them with other people too. You can also view other photos and comment on their photos. This is an amazing way to meet new people and connect to people all over the world that you would never have had the ability to do in the past.One website I just began using is Pintrest. It's great for reading articles and 'saving' them online to read later. Also, goodreads is another favorite of mine. You can get recommendations from other people on what to read and how good a book is. Also, you can write your own feelings on books for others to read. You can also rate the book.
