Janeway posts coffee, dogs, space phenomenon and every once in a while a drunk post that Tuvok deletes immediately but Tom always reblogs first.
Chakotay posts Quotes of the Day, mindfulness tips, pictures of nature and photos of himself with old Maquis friends.
Tuvok claims to not have one but secretly follows everyone from a tumblr called “ask Voyager’s Senior Staff” that answers asks for the Bridge crew and memes. He can also hack into everyone else’s, as necessary.
B’Elanna changes her username every 90 days or so, routinely deletes posts or her entire blog on a whim, has been accused of being a Social Justice Warrior despite at least 80% of her posts being about robotics and engineering.
Tom posts gifs from 20th century TV shows, cars, and shuttlecraft races. And he’s the meme king.
Harry posts performances of Jazz musicians, pictures of Earth, and things he knows the others like tagged with their usernames.
The Doctor posts daily health tips and weekly articles on disgusting medical issues that could happen to the crew if they DON’T COME IN FOR THEIR DAMN VISIT. Also political statements about being alive.
Neelix posts candid photos of the crew, fairy tales from various cultures, recipes, and images of Kes that walk the line between cute and creepy. He also reblogs all of Chakotay’s quotes and The Doctor’s tips.
Kes posts photos of all the interesting species they’ve encountered as well as flowers and plants. Also kittens and kitten equivalents.
Seven doesn’t understand so she just posts her official logs. Janeway tries to explain so she starts posting coffee, dogs, space phenomenon. Janeway sighs and tells her “Seven, NO, things YOU like” so then Seven posts pictures of Janeway. She also posts about Janeway’s service record, which Tuvok promptly deletes starting a war of tumblr attrition because Seven doesn’t like her things being tampered with, even by Tuvok. Eventually he explains to her why her posts are inappropriate and while she disagrees, she stops out of respect for authority.
