Before there was Facebook, Twitter, and Tumblr, there was the finger protocol and the finger cmd. The finger cmd was created in 1971 and an RFC (742) came later in 1977. You provided your status updates using a .project or a .plan file in your home dir. The contents of those files could be queried by other users. The origin of the finger cmd is best explained by this posting to the newsgroup alt.folklore.computers from 1990 . Was this the birth of micro blogging?
