Daytum comes to us from the data obsessed minds of visual designers, Nick Felton and Ryan Case. Felton is the creator of the Feltron personal annual report that we Tufte/stats junkies love and Case is the creative director working on the social media experience at Sling Media. DAYTUM is a wonderful evolution of the personal annual report, bringing obsessive loggers a place to count whatever comes to mind and visualize that data beautifully in the personal and community space. The the UI and visual design are clean and simple and let the data tell the story in sparklines, pie charts, bar lines, line graphs, and big bold numbers. Love it. Hope to be able to generate my annual report after a year of logging.
