I don't know shit about either of the sites other than that there's fanfic there, but my reading of the post is the other way around. I'm pretty sure they're saying that:
Wattpad enforced stricter standards than AO3
Presumably Wattpad's userbase diminished as a result
Now that Wattpad has died or something, the people that supported Wattpad's stricter standards have moved to AO3
Those people now demand that AO3 enforced Wattpad's standards
To be honest, one of my sources of confusion is that the second paragraph suggests Wattpad users are trying to make AO3 allow their type of content, but the third paragraph/second post implies AO3 is too permissive for Wattpad users. The two messages seem opposite each other in what they get across.
One possibility that had occured to me was that AO3 is too permissive for Wattpad users in terms of classification, but that AO3 was a fanfiction site and Wattpad maybe has a mix of fanfiction and OC and that they were annoyed at the OC not being allowed. That would seem to reconcile the mixed messages. But honestly there's nowhere near the evidence from these posts and what little I already knew about the sites to be even remotely confident in that conclusion.
There's a long history of wider fandom spaces becoming profit driven and then purging "problematic" content in order to appeal to advertisers. Someone can write a story with rape because they think it's hot, and someone else can write a story with rape as a way to help process personal trauma, but both are removed because the content restrictions boil down to "all rape stories are bad." This type of policy also tends to affect stuff with queer themes disproportionately.
Sounds like Wattpad has just gone the way of LiveJournal, FF.net, & others by implementing sweeping content policies.
AO3 was created by a fan-run non-profit to be a written works archive with very minimal restrictions on content, but younger folks coming from these algorithm-based platforms aren't used to having to curate their own experiences via filtering tags & warnings. It's the old have your cake and eat it, too problem.
As a very inexperienced AO3 user, tha tags are a nightmare. There's like millions of them and no real rhyme or reason to them it feels like. Plus, people use tags as a joke the same way people did on Tumblr. So it's hard to know which tags are jokey one-off tags and which are tags you should actually sort by.
But, I also understand that for the true users of AO3 (I only ever go there to read stuff people send me) it works good enough and I'm not suggesting they should change it.
Ehh, I'd say it depends on what you're looking for. I definitely get it being overwhelming starting out.
Tagging quality varies a lot, but most weird tags that are fandom, character, or content get consolidated under a broader parent tag. If you're looking for a specific trope or vibe, it might be easier to view works under that parent tag, then filter down by fandom/characters/ship, etc. Also helps to sort by bookmarks or kudos (likes); there's usually a pretty good overlap of popularity & quality.
But I'm a browser & pretty content to just see what comes up, so YMMV. For more specific stuff, the advanced search is also very robust, especially using search operators. There's guides out there on how to get the most out of it.
There's also bookmarks and collections, if you're wanting stuff vetted by another person. I tend to figure if someone wrote fics I like, they probably read other fics I'd like, so it's usually worth a look.
Ahhhh, okay. I didn't know that was a thing. That's exactly the sort of thing that would help though. Tha is for telling me. In Stack Overflow (not that I'm suggesting a technology Q&A site and fan fiction site need similar functions) tagging is much more strict. They can even change tags and combine them thus affecting all related questions. But it sounds like AO3 has something somewhat similar but I wasn't aware.
Haha, yeah it's a neverending process. There's a bunch of volunteer positions behind the scenes; tags are managed by 'tag wranglers', so it can take a while for some of the odder ones to get classified as it's human people doing the classifying. It's a tricky balance of functionality & maintaining the community culture/flavor. I think they do alright, but I've also been using the site for years, so definitely biased.
