There isn’t really much ettiquette that would be nonstandard (such as be nice to people). But not everyone follows it anyway.

Its unclear what exactly you want from this. “Joining the community” is very vague and kind of not possible. There isn’t just one anime community. There are many groups, and while they may all share anime in common that doesn’t mean they all get along with each other. For example, some language groups don’t like others (and sometimes it’s justified, sometimes its not the language groups fault because the translators did a bad job or changed words from the original creator’s work usually without them explicitly knowing, etc). Its kinda like saying you want to join the Lemmy community. What exactly do you mean by that, or better, what are you looking for? Some instances dont get along, some communities on the same instance dont get along, some people in the same community dont get along and form their own on the same or different instance.

So what is it you want? You say to “discover anime and get more into the trends, etc.” Well the first part is simple enough, but what does the second part mean? You want to know what the current trends are? Past trends? You just want a sampler suggestion of different kinds of anime that showcase different trends? This is unclear.

I am happy to make suggestions (though my suggestions skew older and more cultured than modern offerings tend to have, but I do like some modern stuff), but without clarity on what you want I wouldn’t want to offer something you don’t need or care about.

There’s a site called anilist.co you’ll find practically any anime series out there.

Since anime is a medium, don’t be surprised if someone loves a series you hate or vice versa. It’s like books, you know? And for recommendations it’s often useful if you list some series or genres you enjoy.

Unboxious’ recommendations look fairly good IMO. I’ll add a few ones:

• Suspense: Uzumaki
• “Innocent” fantasy: any movie from Studio Ghibli, specially Sen to Chihiro (Spirited Away), Kimitachi wa Dou Ikiru ka (The Boy and the Heron), and Tonari no Totoro (My Neighbour Totoro)
• Darker fantasy: Kimetsu no Yaiba (Demon Slayer)
• Mecha (big robots): Tengen Toppa Gurren Lagann
• Isekai (transported into another world): Log Horizon
• Mystery/“detective”: Kusuriya no Hitorigoto (The Apothecary Diaries)

Remember to have fun. Watching anime is supposed to be enjoyable; if for some reason you aren’t enjoying a certain series, there’s no shame on dropping it.

Usually it’s said three episodes is enough to know if you’ll like a show, but sometimes a single one does it.

Also, watch out for people shitting on the others’ tastes in social media, it’s simply better to block those.

In some cases you enjoy the story and characters of a series, but the production sucks really bad. In those cases, it’s worth to check the manga or light novel series the anime is adapted from. (Hoshi no Samidare, I’m looking at you. Such amazing manga series deserved a better animation.)

It’s worthy to dig into Japanese culture. It makes you enjoy what you see more. And if you’re into cooking, making the dishes you see in anime at home can be a really fun way to experience a bit of that culture.

The “no life weeb” stereotype doesn’t hold true any more. A lot of us have jobs, children, social life etc.

Some people flip the shit out if you use a plural -s in “anime”, “manga”, or “pokemon”. You can either avoid this or to pre-emptively use it to detect and block pass-aggro people from social media. (I never did the later in Lemmy, but it works).

Every sunday night (from my perspective in Mountain Time anyways) there’s a discussion thread posted to /c/anime where people talk about what they’re watching and whether they’re liking it. You can go there and post a comment or reply to someone else. Of course you can do the same in other threads as well, but I bring it up as a good place to start.

As for what to watch, there are a few ways to find stuff. One option is to just look at the highest rated stuff out there and just pick some random thing that looks interesting. Another option, especially if you want to keep up-to-date with stuff that’s being currently discussed, is to watch videos from channels like Mother’s Basement and Gigguk. Right now at the start of a new season a bunch of new shows are just starting to air, and so in a week or two both of those channels will have videos out pitching their favorites to viewers.

If you just want something to watch without needing to do any research here are my favorites:

• Fullmetal Alchemist: Brotherhood for action/adventure
• Kaguya-sama: Love is War for romcom
• Redline for a sick movie about a deadly car-racing tournament on alien worlds
• LOOK BACK or Journal with Witch for something more emotional

Sadly, the community died a long time ago. Nowadays there are just isolated camps throwing shit at each other and normie tourists

Just stay away from the isekai trash or anything that has title longer than 3 words and you’ll do fine.
