As discussed on GS in 2012, Agosto had a leadership role on the local organizing committee for Skate America in Kent, Washington. Agosto was featured in articles, photos, etc. Re his personal life: Pandora was one of the sponsors, and Agosto appeared in a promotional video selecting Pandora charms for a bracelet for his girlfriend. (I'm 99% sure that at the time, she was referred to as his GF, as opposed to wife or fiancee. Possible, of course, that since then they have married -- I have no idea either way.)
B/A were SOI regulars up until then, I believe.
Apparently Belbin is ending her self-imposed hiatus (at least temporarily?).
