Twitter is a great tool for so many reasons, no matter what you are interested there is bound to be content out there for you – politics (@MPRpolitics), news (@WJON_News, @sctimes), sports (@StCloudRox, @Twins), etc. But one of the most innovative used I’ve come across is the “live” tweeting of events from World War II. @RealTimeWWII describes there work like this “Livetweeting the 2nd World War, as it happens on this date & time in 1940, & for 5 years to come.” It allows followers to step back in time and peer at the events of history in a really interesting way. If you have any interest in history I recommend you check them out.
