I like the idea of predefined / selectable post #tag and user defined #tag in comments.

Believe there should be a question type tag for a post that allows the OP or the moderator team to apply 1 or more answer type tags to the comments.

I think it is important for a community to decide which tags will be mandatory, and if they are, requiring the post to have at least one of those tags before submitting (esp for fan communities where spoilers can be a thing). Reddit does this in the worst way possible and should not be a model.

When posting content, community specific tag guidelines should be visible.

It will be important for tags to work from both mobile and laptop views.

DO NOT USE THAT TERRIBLE LANGUAGE DROP-DOWN. Use chips.

A community should be able to optionally define up to three tags as hot / hotter / hottest (in order) to encourage content.

Tags should have colors.

Community specific tags should have limits (3? 5?) so that users don’t have to deal with OCD mods.

Communities should be able to decide which instance tags do and don’t apply—don’t force tags in a community.

When viewing a list of posts in a community, I should be able to select tags to filter posts.

When viewing a post, I should be able to select the tag to see a list of other posts in that community that also have that tag.

Finally tags should be multi lingual. Even community ones.

Great as I don't like Github and dont have an acxount there I'll try to make suggestions here. I'll refer to this comment for further clarification.

• As already discussed in the github issue tags should imo be the lemmy implementation of hashtags as they can be seen on mastodon. ActivityPub already handles them well and on the lemmy side it's just a matter of redesigning in order to display them as more reddit like tags. We have the moderator tags which look pretty nice already. Also important tags like the Mod or NSFW tags could be displayed in a red or orange color which signalizes the importance of the tag.

• My second suggestions was also already pointed out but as on reddit communities should be able to predesign some tags that the users will be able to select (just like on reddit). Additionally users should be able to add maybe up to four other tags to their post the number would have to be discussed with the community to prevent tag spamming.

  Adding user based tags should not be a big problem for moderation as on mastodon anyone can give themslves any hashtag they wan't which seems to work well. Additionally (community and even instance) moderators would have the ability to search for inappropriate tags in bulk which they can then further analyze and remove if it contains inappropriate language.

  These user based tags could be displayed in a small field right below the post body wheras the important tags as well as the community picked tags would be displayed above the post just like on reddit. In a further step an option could be implemented to hide the user given tags entirely or just collapse this field.

Yes totally needed.

I dont get Mastodon at all, posting random content just out there. Twitter was a horrible platform to copy I dont get it.

On Mastodon tags are the only way to filter useful content. On Lemmy you have forums but sometimes duplicates, so tags would be great!

What is the priority for this?

Better mod tools, scanning uploads to combat illegal images, and ways to combat bad actors in general are needed long before this.

Tags should be set up in the community settings. That way there is a community specific list to choose from when posting.

It's a good idea.

I would say that so long as communities are governing their own tags but it's somehow monitored to make sure two tags don't mean the same thing it could be a real positive, especially for support topics etc.

I would love to see tags. This could be used like post flair on reddit, and to search or block specific content and to find new communities.

That would be awesome! We really could use something like flair on Reddit.

I think it may turn out to be useful if besides posts and comments, communities could be tagged too. The moderators of the community would select the appropriate tags, but only from a set defined by server admins.
This could help with discovering similar communities, among other things.

Personally I think communities should be tags - lobste.rs style. You would have tag mods determining whether a tag belongs or doesn't, and it'll increase participation in the comments since everone interested in the post will be discussing it in the same place (nifty, as lemmy is still growing). Cross-posting always felt like a bolt-on solution. It also addresse the issue of cross-instance content preservation in case of outage better

That'll be a great feature. Some notes:

Tags should not be arbitrary text, but instead predefined per community. This would help with automation tools. E.g. spoilers, NSFL/NSFW distinction, trigger warning etc.

Yes because I like Tumblr more than Reddit. I like searchability, and while it can lead to Brigading, is often better for communities with useful information (tech, hobbies, DIY). I think basically some communities should be allowed to turn off any functions that make content more searchable, if they feel they need it to prevent brigading.

I'm really hoping Lemmy can become a little more personal... this threaded communities concept based almost entirely on Reddit does not facilitate 1 on 1 discussion. At best, someone will add a very useful comment to a thread and if people see it then it will rise to the top and be directly under the post. I think maybe being able to star/pin a great comment (like youtube) would be best, but again tumblr deals with this using Reblogs. Just... add someone elses's comment to the post and share it with those comments added.
