Several of my friends have blogs set up on Korean websites. Empas, naver, and cyword are probably the most popular. In the states, the rankings of these blogs are pretty bad. Not really sure how people monetize blogs in South Korea but i bet that its easier to try to make money here in the states. Blogging on a free hosted site is always a bad move. It’s easy and you don’t have to deal with learning much, but if you have a site that people click to, then you are losing out on some money. Important to invest some time and a few dollars to host your own site cause you never know if your blog becomes a hit. Look at blogs like Engadget and Gizmodo. Perezhilton makes a million a year.
