Facebook and Twitter are commonly used, but they are not the street corner. These things didn't exist when the first amendment was written, but printing presses did. And they specifically did not write in a requirement that printers should print anything and everything. In fact, just 8 years after the first amendment was ratified they passed a federal law banning printing of "false, scandalous or malicious writing". And that was fine, because people could still yell on their street corner or write their own letters, which you will always have the right to do.
