Design Patterns discussion

[Jesús Alonso <kenchoweb AT hotmail.com>]

Yes, completely agree with Ajay. Patterns are great solutions for many 
problems, but they are not the panacea. Applying them blindly just thinking 
that they will magically do a great design is really the worst one can do.
I was a pattern-fan when I learned them. I simply tried to apply as many 
patterns as I could. Now, I do simple designs, as I used to do, and when I 
identify a certain problem and know its solution, try to identify some 
participants in my design and then apply the pattern to complete the design.
