a side note on the high art of casting the ordinary trivial, into something special
This does not mean that what Risteski wrote on the guitar is not of value. Of course there may be interesting things there. Same with other methods, etc. But this whole topic (guitar pedagogy) seems to be one, where I can get information from anyone, even my neighbor. In other words: The body of knowledge related to guitar pedagogy is, to a great extent, not specialist knowledge with easy categorization of the sources of various ideas. Hence I detest when Risteski writes "this work will introduce a new guitar teaching philosophy on the virtue of musical-aesthetical knowledge of classical guitar music". What he wishes to display as something "new", is rather something that I could easily learn and find, while having discussions with my friends, with a glass of wine. So 'cheers' to guitar philosophy!  

At the same time, I can look at the article and see it empty. Risteski's articles can at least provide some food for thought; and that would be a reason to include them in the external links. I suggest: let's mix a cocktail of philosophical guitar pedagogical content. Add sugar to taste!   
writing articles for wikipedia is different than writing a "term paper" for school or a commentary for a newspaper or a book that you wish to have published. In all of those occaisions you as a writer are supposed to look at primary sources and material published by others, analyse them and put them togehter in ways that support your original thesis. Taking that approach to Wikipedia articles is not acceptable as it violates our no original research policy. For Wikipedia articles writers must take material and analysis that has already been published by others and create and article that reflects all current thought on the topic, giving appropriate propotion to each. 
And again, tagging an external link that does not meet our guidelines for external links onto the end of an article that is not in good shape is NOT an improvement to the article. The Red Pen of Doom
