SharedCopy
SharedCopy was an AJAX based web annotation tool that allowed users to mark-up, highlight, draw, annotate, cache, sticky-note, and share any website.
Founded in March 2007, SharedCopy was reviewed on TechCrunch, Lifehacker, Killer Startups, Startup Squad, and The [Wall Street Journal]. Initial user response to the system was mixed. Some reviews were positive, but others complained about bugs that were eventually fixed.
The co-founder of SharedCopy was also nominated by Businessweek for Asia's Young Entrepreneur 2007.
