We're only mad at Evite because we need it so much and we know it could be so much better. The site, in short, is crying out for an overhaul. With more and more sites emphasizing flexibility and user control over content, Evite's fill-in-the-blanks approach feels clumsy and dated. The ads are intrusive, and navigation's a drag. The service has also been slow to adopt some of the media-sharing tools that have become standard ways of the Web. You can upload photos, but only after the party, and you can forget music and video. The company says these features are in development. We can't wait.
