User blog:JoshuaJSlone/Post-Michishige Seniority

With so many new members and a major graduation, I thought it would be interesting to see how the seniority all shakes out now. In general I'm ordering things by the date they were announced to be part of a major group (sorry ZYX and Aa! members) and then by age. I'm not listing Mitsui Aika because the part of me that does that is on hiatus.
