Miss Emily is hiding.

Miss Emily's blog would epitomize her private, secretive attitude towards the world. She would utilize all of the privacy settings available to make sure that no one except her "friends" would be able to see. She would only be friends with Tobe, Colonel Sartoris, Homer Barron and her relatives from Alabama. There might be a few photos of her silhouette or shadow through the window that had been taken and tagged by other people, but no photos of Emily taken by herself or those close to her. Emily would have applications for photos (that others have posted), a calendar (to measure time slowly passing by without external human contact), groups (to join an art group because of the classes she taught), and the likeness application (to show how well she matched up with Homer). Miss Emily would probably not have conversations on her wall because that is too public, but she might have conversations via messaging.

Colonel Sartoris: Dear Miss Emily, I would like you to know that you are and will always be exempt from your taxes due to the great service provided to our town by your father. Regards, Colonel Sartoris
Emily: (20 years later) Dear Colonel Sartoris, I have been receiving inquiries regarding tax collection from the town and have sent them back to the post office immediately because you said that I am exempt from taxes. Please verify this information. Thank you. Regards, Emily

Emily: I am having a lovely time with my significant other, Homer. Everything is swell. I hope everything is wonderful in Alabama. Love, Emily
Grierson cousins: Emily we are coming to see you and meet Homer. The mayor of your town has contacted us and we just want to make sure everything is going well. We cannot wait to see you. Love, cousins
Emily: It is absolutely unnecessary to come see us. I am sure you will get to meet Homer in the near future anyways. PLEASE do not come to town. Love, Emily

Miss Emily is clearly a private person judging by the fact that she never leaves the house after her father's death. She also neglects to have visitors over other than Homer who ends up living with her and Tobe who is her servant and lives with her anyways. Because she is so reserved I doubt she would have a facebook page in the first place as facebook was intended to be a networking tool and she clearly does not want to connect to anyone that she does not have to. If she did happen to have a facebook page it would be completely private because she was such a hidden woman. She would not have very many friends to respect her need for privacy and prevent town gossip. The calendar feature of her facebook page would record the day she poisoned Homer and her slow aging process, leaving her daily reminders. It is hard to create a definite description of Miss Emily because she was so secretive and William Faulkner tries to retain that discreteness in his description of her. We know little about her because the story was told from the perspective of an outsider who clearly did not know her very well, but knew her primarily from stories told by others. The image painted of her is fairly vague and prevents her from having a more exciting or elaborate facebook page.
