Looking for Opinions: Marketing question about my map.

[Nicky_Da_B]

Hey mapmakers. So the other day my Star Wars Left 4 Dead 2 map was featured by some youtubers. I didn't reach out to them, they just found it and played it I guess. But they have a huge following, and I saw a bump in downloads after the video was released. 

So it got me thinking about marketing my maps and what not. I was wondering, do any of you do marketing for your maps? Do you reach out to people and say "Hey try my map!" I'm wondering if there is something here to increase downloads or become famous or something. Like how do you help get the word out that you made a map? 

Thanks in advance to all who reply with feedback, opinions, and thoughts.   

I included the video for reference.
