Here is the Twitter hashtag for Digital Wave – #digitalwave
So what's a hashtag? First, it has the pound sign at the beginning. Second, it compiles all the tweets that contain the hashtag. The result is that you can group all the tweets around a topic or conversation simply by including the hashtag in the tweet.
