there are many ways to use a camera, and unless you are shooting challenging light situations, you may be just fine using JPG output. Why complicate life unnecessarily?
Now please can we get back to FILTERS vs. NO FILTERS?
edit: I clicked on your gallery to see what kind of shooting you do, but most of the image placeholders did not have a visible image (at least for me). Among the three images I saw, this one would have benefited greatly from some highlight recovery and lifting of shadows using RAW:
there is also a purplish looking sky which could be adjusted a little better using RAW processing.
Just trying to give a practical example to your question.
