It is not a piece of software or a thing to use, but it is a set of repeatable components that you use in whatever app you are writing. Take for instance an observer pattern. When would you use that? Why would you use that? Have you used it somewhere before and what were the circumstances? Is it repeatable? Is your previous code re-usable? Answer some of those questions, look up design patterns (even on wikipedia to get an overview) and buy some books to see solid examples. If you suspect that you "need" to use a specific pattern, or are interested in how to implement a specific pattern, write some throwaway code to do it and ask opinions. Look at the simple things that you would probably have used already - factory, singleton and MVC and expand on those a little to get them to be actual design "patterns" that you can use/reuse. Don't "use design patterns" because you heard it on TV - same as "Web2.0" _think_ about what it means to you and your enterprise before asking for a buzzword generator to do your job for you! :) --Paul
