Fireman25 was definitely snubbed. But then again, I feel like his impact was more related to the 2000s than the 2010s. I joined here in 2008 and he had more of an active impact in 2009 than I do remember in the last four years.
Fireman, for sure. Surprised Cap10, MP2K, 1-N-only21, Eli, Talisa, Kh-Loud, and Keir weren't included. I joined in 2009 but they were still key members in the new decade.
