(this has been done before, but who cares?)
breq: 90% reblogs of videos of ordinary people singing things, 9% earnest discussions of developments in the field of ethnomusicology and dry critiques of the colonialism and racism and anglocentrism and americentrism of same, 1% very subtle trolling. it’s a low traffic blog, so the trolling’s hard to spot
seivarden: the shitposting is fun, and the reblogs of pretty naked people are okay, but watch for the periodic public meltdown and deletion after she gets called out, no matter how mildly.
ekalu: carefully curated blog of things that she likes, notable for studiously avoiding tumblr drama
basnaaid: mostly sustainability and aquaculture posts, some reblogs of cute succulents. went through her blog and deleted all the embarrassing original poetry posts long ago, but the internet remembers, basnaaid!
uran: language learning and local politics. has a private tumblr for the anti-radchaai sentiment
kalr five: what do YOU think?
dlique and zeiat: every few months they do this thing where they change their urls to each other’s names without warning, and at the same time each posts the sort of content the other usually posts (both surrealist, but in different ways, in both cases running from subtly disconcerting to wildly disturbing and not safe for lunch) thus breaking everyone’s links
tisarwat: somehow wrested her new url away from anaander mianaai, who was using it to stalk breq after breq blocked her. is now making a very calculated (and successful) attempt to become Tumblr Famous.
sphene: hates tumblr, misses hating livejournal.
anaander mianaai: her first ever post was this inspirational graphic with the mantra I AM ALLOWED TO TAKE UP SPACE. which in most cases is a harmless and beneficial motto to have, but less so when the OP is anaander and she means she is allowed to become an interstellar dictator, clone herself thousands of times, and annex as much of known space as she can. there are twenty thousand reblogs. the first five thousand are all her.
