The document discusses social media conventions used by two musical artists, The Pixies and Bruno Mars. The Pixies use a group long shot as their profile picture and save stories with various media formats, including 3 blue theme pictures. They incorporate merchandise into posts but don't share much relatable content due to their older audience. Bruno Mars uses a close-up profile photo with direct eye contact and advertises his music in his bio. He adds a comedy element to make his page more relatable and mixes close-up, longshot, and group shots with promotional tour posts and brand deals.
