Want to create your own embeddable content?  Flashy storytime advert? Library news flash widget? Then you must try Sprout, an incredibly easy and totally awesome "widget" builder--although for our purposes, these are known as "Sprouts".  Without really putting too much work into it, I created a Sprout of my library's blog, @thelibrary, and embedded it here:

Select a few features, change the color, adjust the font, publish it and viola, you get your own homegrown Sprout code to embed and/or post to Facebook, MySpace or several other networks. Think of the possibilities and go for it!
