'''Clipstart complements your photo application to give you a place that is designed for home movies. Import your movies, tag, search, and upload with one click to Flickr and Vimeo.'''
Manton says more on his website, but I think Mr. John Gruber describes it best:
'''Back before iPhoto existed, I used to store all my digital photos in folders by hand, using the Finder as the management tool. That’s what I was doing for Flip clips before Clipstart, and at this point, I can’t imagine going back.'''
