Why is there so much hate here? Relax.
Assuming your way is the only and best way, is silly. Assuming that if someone does it any other way, they are automatically a "wanna be" is both ridiculous and insulting.
If you don't want to use a plug-in, by all means stick with your methods because they work for you. If somebody wants to take an alternate method that they get satisfactory results with, why shouldn't they?
Photoshop is an extremely powerful tool, but it is not the be all end all of tools, it's a strong base. Do you still use photoshop to enlarge an image? Do you use only photoshop to reduce noise in an image? It could be argued that doing either of these exclusively within photoshop is actually the 'wrong way' these days as there is software (*gasp* plug-ins) that do it far more effectively.. both faster and better in some cases.
Anyway, relax people, we do this because we enjoy it right? Even those of us who do it for a living, I hope are still in it because it's something we enjoy. You shouldn't argue about something like that
