Right now, I am waiting in the Jeju airport to fly back to Seoul. Fortunately, they have internet terminals that are free to use. One quick idea if you are interested in learning more about popular culture and what is hot on the web:
Check out the history section on the web browsers at public places!
You can do this at the Apple store, libraries, airports, etc… It is not good to try and figure out interests of specific demographics but this should give you an idea of what is hot and being used by the general public.
And before I board my flight I will leave you with this wonderful quote from my gf:
I’m sorry I’m not one of your “loyal” fans who reads your blog every single day. i am dating you, not your blog. quote that.
