Oh man, this is a great question!
…but I am maybe not the person to give a great answer. Sorry…
I actually don’t follow a ton of blogs, and the ones I do can be broken down to 25% that are peeps who have nothingwhatsoever to do with dramas (*waves to the NA brigade*), 50% that are single-serving interests (music, actor crushes, bats, funny stuff, news, Hoya, etc), and 25% that are peeps who are in the drama fandom but that’s not necessarily all they post.
I spend more time hanging out in specific tags to find drama-related stuff to reblog. That’s because I really haaaaaaaate being spoiled on shows I’m watching (or planning to watch) and it makes it easier for me to avoid spoilers and select just what I want, when I want. (The trick to avoiding spoilers on the dash from the kdrama peeps is to apparently watch the shows that no one else is watching, which seems to be working for me so far.)
Just double-checked real quick and yeah, the only kdrama-centric blog (that doesn’t also double for a personal blog) I currently follow is @undergroundkdrama.
For more suggestions, I’ll link to a couple of recent posts by other people that are undoubtedly way cooler than I am. I recognize a lot of the names there, and the ones I recognize are pretty commendable, so I’m just assuming everyone else is, too. (And I should probably check them out, too. It’s been so long since I’ve done a follow-frenzy!)
