For an Informed Love of God
The orange icon is to indicate a RSS feed. This is an older technology that is still useful. Instead of you having to come to BillMounce.com (or any site with a feed), the RSS feed pushes its content to you.
For this to work, you need what is called a "RSS Reader," an app that knows what to do with the feed. If you just click on the icon, you will see the feed itself, but that is not much good to you.
There are many RSS readers out there. I use Feedly and the all-purpose Thunderbird from Mozilla. There are also apps that be used as part of you browser. Just google "free rss reader" to see the options.
Enter "billmounce.com/rss.xml" as the name of our feed in your RSS reader, and you will be sent our blogs and the Greek Word of the Day.
