No - and I'd also challenge the assertion that Dropbox and Slideshare are mainstream anywhere outside of the tech/early adopter community. These (and online docs) are products that people who like technology and new things use as a way to get their work done. The vast majority of people - and this is especially prevalent in enterprise contexts - don't care about a new way to get their work done, since the old one seems to work fine. Want to collaborate on a document? Either use Track Changes or press the "Share on SharePoint" button in Office. Want to share a PowerPoint? Email it. Want to version a document? Load it into the company's knowledge management system. I work on a leading-edge team inside of a very progressive (enterprise-size) company, and it's a battle to get people to use the wiki we have set up.
