Today is the two-year anniversary of ThoughtLog. You no longer have to write things down, ThoughtLog reads your brain waves and automatically writes down all of your thoughts, for free! “Sponsored Thoughts” from our advertisers are minimally invasive and can even be fun! We are working on VisualLog to record everything you see. Another free service, this one provided by "Visual Billboards" that place advertisements unobtrusively in your visual field.
