sendmail vs mailto: links for viral content sharing?
qhoxie: 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?
