Delta lets people semantically describe the past, present, and future. Based on these descriptions, Delta understand intents and can help you make your wishes become reality, by connecting you to people that offer solutions to your problems.
Most companies do that, but they imposse themselves domain-specific limits. Delta has no such limit.
Delta should be able to replace the functionalities of most web companies, such as Facebook, Google, Amazon, Craigslist, Asana, Freebase and even emails.
