I like that it gives you control over how much information to share with advertisers or other websites (using the "Do Not Track" setting) by allowing only certain domains access to the data stored within their browsers' profile pages through its software. It also has an easy method of linking users up with friends who may have used this service before; however, there's no direct link from me to any former colleagues at my current employer. And if they were using the same platform as myself, then our profiles would be linked which isn't something we want right now. We've been able to keep all relevant company info private while still maintaining some degree of anonymity when needed.
