It pretty much rocks.
You put up a late-night tweet mentioning a favorite musical artist. The next day, said artist replies. You then find out she has — at long last — a new album coming out. Later, you’ll pre-order the new album on iTunes or Amazon, and it will magically download itself into your library or show up at your door on release day.
Actually, I’m not sure if I’m singing the praises of modern networking, drunk-Twittering, or both.
