(Maybe we should wait for more examples of different types.)
Okay, I switched the order according to Sebastians's suggestion. Please note there is just one logical forced order (which I will have to correct now):
```
		} else if (testString.indexOf("website") != -1) {//"Blogs, Podcats, & Websites"
		   guessType = "webpage";
		} else if (testString == "blog" || testString[i].indexOf("article in an electronic resource or web site") != -1) {//"Blog", "Article In An Electronic Resource Or Web Site"
		   return "blogPost";
```
