Hallelujah the hashtag is explained. But first, when did the # symbol get renamed? Does the fact that I had no idea the symbol-formerly-known-as-pound is now called a hashtag mean I am hopelessly behind the times? In any case, I learned that the hashtag is a way to tag Twitter topics, thus making it easier to track, search and organize topics of interest. However. How to actually make use of a hashtag remains a mystery. Apparently if I were, say, a frequenter of after-parties the use of the hashtag would be crystal clear. It's all too advanced for me and I am regretting jumping ahead to the hashtag portion of the tutorial.
I humbly retreat.
