Saw the video demo... i don't see how greppage is any different from the usecase they were saying it solves (googling). You still have to search, you still have to view the search results and choose a result and then view the chosen result... Its a small marginal improvement that isn't big enough to warrant it being another tool one has to remember and use.
This is a cool idea. Could we use github repos as the training data?
sounds like a great way to get a morass of code spaghetti as quick as possible. "what does this module do?" "i dunno but it makes the webpage load really quickly without me having to optimise!" "why is it 2 years old?" "because when i replace it with anything else, load times jump by a factor of 2 across the board and i dunno why"
