SSL on your website
I strongly suggest you add SSl (https) on your website. It takes you 5 minutes to do, and your hosting provider will usually give you the SSL certs for free.
Most importantly, your widgets should use SSL so we can embed them in https websites. Privacy and security are important and I want to know that the widget I use is actually from your website!
Agreed, and this should be added for all links on the website. Right now when clicking links on the website, I get downgraded to plain HTTP. This is important because the GFW in China blocks these HTTP links sometimes. (this website is sometimes unavailable on http, but usually works with https)
