I use a couple of Browsers daily to search for things that interest me. Medical Info--History--World Events and News. As a resident in Assisted Living I have found the net to be a great way to pass time and stay informed. There is of course reliable and unreliable info, so caution!
Indeed I do, in two languages. I'm an early bird; I start in the morning with google news. I like a professor's blog: 'Informed Comment.' In addition to the local newspaper (Gainesville Sun), also read Huffington Post regularly (Google News is available. in a number of languages, including German, from Germany, Austria, and, believe it or not, Namibia!!! (German colony until WW1)
All the time. I use it a lot for food. When I used to do hard copy crossword puzzles, I kept a dictionary at hand. Now that I do them online, I just highlight a word I'm not familiar with, right click it, select Search Internet, and I'm a little more informed.
