Bloggers: Download a WordPress plug-in [future development] that will take any post you have where you reference a verse and instantly index it in YouVersion.
Tag verses with latitude and longitude coordinates that reference where events in verses took place (ie: birth of Jesus in Bethlehem), and then use Google Maps in a mashup to create a map of the verses of the Bible.
Email this scripture to someone who just recently lost a child. (Lamentations 3:18-23)
Pastors: Link your sermon outlines to each of the verses that are contained within.
Journal the things you are learning as you read the Bible to avoid having multiple notebooks and places to record those words.
