You should make a starcraft 2 playlist! Just browsing your videos right now I don't currently see any arcade ones, so maybe when you make your first arcade video you could create a SC2 Arcade playlist.
Feel free to do any of my stuff. My most popular maps are Stukov - Man or Monster and Stukov and Pals. Nydus Mastermind also has some popularity but you need like at least 6 people to play for a decent match. I've also started a single player campaign called Mapsters (click my name on this forum to check it out), but it's still in progress. So it's up to you if you'd want to wait til it's finished or not. I'm planning on making 6 missions total for it.
Anyways, it's great to have more youtubers showcasing creations! :D
