I've mostly figured out Drupal yet Twitter still mystifies me... not complicated enough? (Being a dispensationalist, I like complexity)
Anyway, can someone who understands Twitter well explain to me what the #this and @that are all about? For example, right now if I go to Twitter.com the home page has some links to things like "Thanksgiving" "new moon" and "#blackfriday"
So why does blackfriday have a "#" ? What exactly makes some "topics" have "#" and some not?
Question 2: I hear people say sometimes, "So and so tweeted me." What does that mean? I see how you can post stuff in a Twitter account but how would you "tweet" a person?
