Having each user do their own sending seems like a more scalable and robust solution to me. But it doesn't seem to be standard practice with similar apps. Any thoughts on why? Are there a significant percentage of folks who don't have an email client set up correctly for mailto: to work? It might be more scalable, but it's (in my mind) not more robust. Most people I know use webmail with no mailto setup. The impact will really depend on your content and your audience. Is your audience savvy enough to Copy Email Address if they don't have a mail client setup? Is your content worth their trouble to do so?
