Keep in mind quite a few people have done this before, bitcircle, 4hoursearch etc... spring to mind but DDG has actually done some innovations in the space and is still around. The fact that people know it will still be around next year encourages you to at least play with it.
Taking the Bing API, building a frontend, a parser for few shortcuts and get some VCs to blog about me?
Sounds like a project from a 48h hackathon.
