Like the idea for this thread. Seoul is an amazing place, and needs more coverage. Just a suggestion but see if you can add the names and some data on the projects that's in English. Many of us are not Korean here. Would make it better so that we can learn about various projects, the architect, building data, time tables, and so on. I do the Shenzhen thread, and even though I'm not Chinese, I use the translate feature (google translate), try to high light important data, and so on to better present it to English speaking people. Example being post #5 and #3. Now those look interesting, but most of us here do not know about those projects, and it would be cool to understand the details.
These being some suggestions, and if done, this thread could be kick ass.
