Hey Twitter(/Reddit) alternative seekers
Okay, fandom. Everyone's all worked all the time about this or that new alternative to Twitter and how it's either awesome or it sucks. I'm here to tell you about an OLD alternative: Plurk.
(Note that this was originally formatted for Twitter so forgive the jank thread paragraphing)
Disclaimer: This information is specifically aimed at people who use Twitter for fandom purposes; it is not intended to cover the exhaustive list of things that people use Twitter for (professional networking, art/photography promotion world news, etc). It's friend-centric rather than follow-centric, at least as the existing site culture goes.
So what is Plurk? It's a threaded microblogging platform dating back to 2008 that has only ever seen extremely niche use in English-language use. (Its primary userbase is Chinese-speaking.) It has a purely chronological timeline and a lot of privacy features that you haven't seen since the LJ era (assuming you're old enough to remember that).
Plurk functions through an exclusively-chronological timeline on your homepage (desktop) or in the app. Algorithmically sourced content? We ain't got it! (There is a different page for viewing top content but you have to go there specifically.) Instead, your timeline shows your own content and the content of other plurkers you friend or follow, and the occasional ad (MUCH more occasional than Twitter).
Each top-level plurk can be replied to, and this creates a chain of replies that can be used for conversation. Unlike Twitter and Reddit, replies don't form branching threads; each plurk is only one stream of conversation. Plurks with unread replies will be lit up as unread; however, they can be "muted" to stop them from giving you notifications.
(Two small caveats: You cannot mute your own plurks, and there is actually a cap of around 200 muted plurks. Mutes will fall off from the oldest, so you'll sometimes see an ancient plurk pop back up on your timeline if someone comes back to it. You can just mute it again.)
Your plurk timeline has a global privacy control. If your timeline is set to private, only people you have friended can see what you say on there. If your timeline is public, then anyone who comes to you page can see what you've posted, AND logged-in users can share your post on their own timeline with the "replurk" function (works just like a normal retweet), as well as reply to it.
There is also an "anonymous" option, which anonymizes you and also the names of everyone who replies (it randomly generates names like "lemon354" and "libra262" for repliers to differentiate them). Anonymous plurks will stay within your timeline if your plurk is set to private, but can be replurked if it's public.
BUT WAIT, THERE'S MORE, because individual plurks can also be given specific privacy levels:
-> Friends only (if your timeline is public but you don't want this one getting around)
-> Private to "cliques," which are Twitter circles but you can have more than one
-> Individual users (including those not on your friends list - this is plurk's equivalent of DMs)
Your own plurk homepage is also insanely customizable, if you want to break out the CSS or even just have a custom background. You can also alter your display name (though the character cap is VERY short), and your display name color, as well as the standard avatar change. Usernames cannot be changed as a free user, but can be changed by paid users (more on paid options in a second).
Plurk also has its own image hosting, and a pastebin-alike plaintext called Plurk Paste that has no character limit. (The character limit for top-level plurks is longer than Twitter's.)
It also has CUSTOM EMOTES in addition to its (somewhat wild) default selection. They're similar to Discord's customs, except that you can use GIFs from the get go; what's restricted is the number of slots you have as a free user. (And size is capped at 48x48 px.)
Plurk has ads, but they're mostly unobtrusive (and can be clocked entirely with ad blockers, but I didn't say that). Plurk keeps the lights on through a subscription model called Plurk Coin, which is very cheap (under $2.50 USD/month) and can be gifted to other users. Coin gives you a number of benefits including the "Except" privacy option, more username colors, response editing, and a bunch more custom emote slots.
Concerned about harassment? Plurk has one of the most robust blocking systems in social media that I've ever seen. You block someone, and they can't see you (even by going to your profile) and you can't see them. That's it, done. Full no-contact.
NSFW/18+ content is allowed. There's a specific flag for it when you first post a plurk. Plurk does expect you to use that tag when appropriate, but is otherwise very forgiving of NSFW content, at least in my experience. (Again, though, English plurk is a very small community ATM).
The thing to remember about Plurk is that it is very much a remnant of an older internet, from the days before algorithms. Like Tumblr, it's a social media where you won't see anything if you don't reach out to follow and friend people. It predates "going viral" as a goal of internet usage. The goal is to talk to people.
As an aside: Since I originally wrote this up, I've seen rumors about Japanese fanarts moving to plurk and even seen one or two mentions of it in the wild on my Twitter timeline as people talk about following those artists. Fantastic! If that's you, then I hope you find this slightly more in-depth guide to features helpful.
If this sounds up your alley, I've made a public plurk specifically for Twitter refugees to come meet people and get more information on how plurk works! You can find it here.
Please replurk to spread this information about!
