Feed-Burning (What Is?)

These icons to the left are called chicklets. You see these on various websites and blogs. They inform you that the particular site you are looking at has syndicated content which can be subscribed to. When you subscribe, content from that particular website or blog is delivered to you eliminating the need for you to go to the website (and saving you a ton of time). The different chicklets are there to provide you with the choice of which reader to use. The differences between them are minor, they all do the same thing (though the underling technology may differ between them).

Kwotebel is syndicated, however, rather than clutter my site with all those chicklets, I use which is a catch all service (located on the right side below the menu/links). Here's more on information on site syndication. You may prefer to check in on the blog directly but syndication can be useful if you frequent a lot of sites.
