I'll give it a personal twist here. First list includes chars I don't necessarily interact much with. Second, chars that are interesting to interact with, sure, but also that gave that click-at-first-interaction feel, to keep the list manageable. Because honestly, I enjoy interacting with SO MANY of you, y'all have amazing chars, and in most cases, interaction grew over time.
Posts I ship to read, fangirl style: Dorne, Alder, Chaffer, Farryn, Pax, Shalistae, Brynhildr, Legacy, Tessa, Tycho, Siol, Sarasa
Chars that gave me that instant click in interaction: Myrist, Lucienne, Callan, Addy, twin sis, Matsu, Myles, Ar'den, Cygnuus, Richter, Coivie, Athalie, Sam, Orion, a few people I never got the names of... or forgot. Fate kept us apart.
