In addition to SMTP there's !XMPP and #IRC, but you're right, they don't have mainstream adoption (unless you consider the bastardized versions produced by Cisco and Slack)
I don't get it... this #efail / #gpg / #pgp / #smime thing is all over German media (e.g. here: http://www.tagesschau.de/inland/e-mail-verschluesselung-101.html) even though it is totally irrelevant for 99% of people, as almost no one is using PGP encryption for his/her mails anyways and the few that do will most likely have disabled HTML emails (or at least loading of remote content).
It would be much more proportional to write a *shocker* article every single day about how almost all emails are sent with no e2e encryption at all.
Even better, extra virgin olive oil or coconut oil (depending on your location). Sunflower is still low quality fat in terms of health, althought better than the (refined) palm oil included in highly processed foods.
@bobjonkman The potatoes are probably the least of your issues. The palm oil most use for snacks and other products are very bad, not only for your health, but also for our rainforest and our wildlife. You should therefore avoid anything with palm oil and only buy products that use better alternatives like the sunflower oil.
