The Korean section is still very silent so I will share a few of my latest Blog Posts to see if it garners some discussion. The series came about because of a discussion I had with another Taekwondo practisioner who felt that looking at deeper applications within the Poomsae was pointless because the originators of the Taekwondo Poomsae knew nothing (his point of view not mine). I then made the argument that I copied below which he did not have a clear answer too. I then wrote a series of posts (4 in total) demonstrating one basic technique (Face Block or Eulgeul Makki) and how it could be applied in various ways. It is therefore not Poomsae applications per se but rather a Gibon Dongjak Application (I believe Poomsae applications should make sense within the dynamic context the technique is presented in). Following is the argument that laid the basis for the discussion and following that is 4 links to the posts:-)
"All Poomsae consists of roughly the same building Blocks as Karate Kata. We agree that Karate Kata had practical Applications. We are both fans of the excellent work that Iain Abernethy, Vince Morris, Patric Mcarthy, Jesse Enkamp and others has put forth on Karate Kata. They all say that each technique in Kata can be several Things however. So each basic technique has several different Applications. Making New forms out of the same building Blocks would therefore be like playing Scrabble With only the white pieces (the ones without letters). They can be any letter you want so eventhough there are New unique sequences in KTA Poomsae that are not found within Karate Kata we can still make Words and sentences With them."
