Document pros/cons vs. competition

It might be interesting to add a page/section about differences with other similar scripts like [be]Lazy for instance. Thoughts?

Yes that's a good idea, I am taking PR on this, I am not actively using lazyload even if it works well.

blazy was done after my lazyload so I am not sure what are the differences. Maybe in the number of edge cases solved.

http://developer.telerik.com/featured/lazy-loading-images-on-the-web/ might be a good resource to start with.
