I have been reading a lot on design patterns lately and some of them can make our lives much easier and some of them seem to just complicate things (at least to me they do). I am curious to know what design patterns everyone sees as underunsed or underappreciated. Some patterns are simple and many people do not even realize they are using a pattern (decorator probably being the most used, without realized). My goal from this is to give us pattern-newbies some appreciation for some of the more complex or unknown patterns and why we should use them.
