Design patterns to avoid
A lot of people seem to agree, that the Singleton pattern has a number of drawbacks and some even suggest to avoid the pattern all together. There's an [excellent discussion here][1]. Please direct any comments about the Singleton pattern to that question. 

Are there other design patterns, that should be avoided or used with great care?
