okay okay but i just need to mention one little thing:
fan site dynamics work like this: twitter reacts first, usually dramatically, thinks later. tumblr thinks first, analyses to see exactly what we're working with here, puts it in perspective with their YEARS of experience in this fandom, then reacts.
therefore if you're coming here from twitter, you should have that in mind, as well as keep in mind a few guidelines that worked great for me as someone who lurked around fandom since 2013 and only got REALLY involved in quarantine:
1) RESEARCH PEOPLE RESEARCH. i don't care if you've been part of fandom on twitter for five years, tumblr has so much more information. on absolutely everything. and it all comes back pretty frequently in some way or another. so, to avoid making the Knowledgeable Veteran Larries want to smash their heads into a wall at every "wait what happened in xxx?" message they get even though they've discussed it 1000 times already, just do your research. @larrytimelines has, as you guessed it, timelines for shit that happened over the years so that may be a good start. otherwise, @daisiesonafield-blog has a very well organised blog (how, i don't know, lowkey suspect she's a witch) so just look through her many useful tags for larry resources and you should be good to go for a nice long while.
2) don't come here thinking you know better than the people that have been around for 10 years. that's the main one. it's as simple as that. these people have lived through the worst stunts, they've seen it all, they know what they're talking about. they know better.
3) if you're gonna be ageist you can fuck off. i've lost count of how many people on twitter have said that after 25, you shouldn't be a part of fandom anymore. you do not lose your interests as you get older. if i see you being ageist anywhere in my or others' blogs consider yourself blocked because i do not have the mental stability to handle idiotic children (and i promise you that it's possible to not be asshole to people older than you. at 19 i'm a baby larrie here and i get along with the veterans just fine so you can do it too, it's really not that hard to be respectful)
4) don't be a dick. don't judge people for liking or doing things that you wouldn't like or do. most recent example is the hs3 leak. don't wanna listen? don't. blacklist the HS3 LEAK and HS3 SPOILER tags and just get on with your life. do not be a dick to people who choose to listen to it.
5) before sending an ask to a blog asking about something, scroll for a bit to check if they haven't answered that question already. or check their blog for key words related to that subject. AND DON'T USE PEOPLE'S ASK BOXES AS GOOGLE SERIOUSLY IT'S ANNOYING WE'RE NOT GONNA FEED YOU EASY-ACCESS INFORMATION ON A SILVER PLATTER YOU CAN GET UP AND GO GET IT YOURSELF (that one is particularly annoying to watch so i can only imagine how it feels to get them) (I just make one tiny distinction: if you've genuinely tried looking for the information on Google, on other blogs, etc. then it's okay to ask for help, or to ask if they have any tips on how to better find the information you're looking for, I just get really pissed when people ask things without even trying to find the information themselves.)
6) go look at just general tumblr do's and don'ts. take the time to do it. tumblr is not twitter we do not work the same way and i don't want my beloved hellsite to get like twitter, as fun as it is at times.
and that's about all i have for you at 8.30am, feel free to add some more if you have anything else in mind, dm me or send me an ask if you want more information on why twitter and tumblr are different as someone who's in both
