NEW YORK (AP) - Twitter is doing away with vowels, Google has a "smell button" and the cast of "Wings" is launching a Kickstarter campaign. The digital world celebrated April Fools' Day on Monday with the annual rollout of mock innovations and parody makeovers. Despite 72 hours of video uploaded every minute, YouTube said it was shutting down. The Google Inc.-owned video site joked that it had concluded its eight-year-long talent search. Having already debuted its wearable Google Glass, the company on Monday showcased "Google Nose," adding scents to it search results. The comedy site Funny or Die parodied the recent Kickstarter campaign for a "Veronica Mars" movie with crowd-funding campaigns for other 1990s shows like "Wings" and "Family Matters."
