I would personally like to see more word mnemonics rather than fewer. I can understand some people being irritated that there are "too many" for a single word, or too many that they don't find helpful, or too like another (which can happen as a previous mnemonic gets refined/improved upon by other users later to be "more helpful"). I myself am frequently mystified why some seem to get so many likes, but they still seem popular. But I feel that we have the benefit of being able to hide ones from our view that we don't want to see.
If a word was limited, say, to 5 mnemonics, I may not personally find any of the 5 personally helpful, and may miss being able to see one I COULD find helpful because it was written after the word reached a 5 (or whatever #) mnemonic limit and so cannot be shown. If I think there are too many, and only want to see 5, I can pick the 5 I like and hide the rest. Then, if another shows up that I find more helpful, I can pick the least helpful of the 5 I had still visible and hide that instead of missing out on the new one. Just as an example.
I can understand not wanting the list to grow too long, however, since it could get overwhelming and/or difficult to slog through. But I don't know what a good cutoff number could be. I would hope that within, say, 20 usage notes, there would exist enough helpful notes that users aren't really as inspired to create more, and it could be rather self-regulating in that regard. Though I don't know if that would necessarily be the case.
As for guidelines about "objectively bad" mnemonics, especially based on pronunciation "mistakes", I have seen plenty that seem to be so far off that the kana in the word seem to have been outright misread by the user writing the mnemonic. But I'm concerned with how strict the pronunciation matchup would need to be to not be rejected. Given the previous example from this thread, if I'm understanding it correctly, using a word with a こ sound for one with a こう sound, or vice versa, being considered "misleading", mnemonics could be impossible to have pass. But maybe I misunderstood that.
There are a lot of words in Japanese that have sound combinations that just don't have exact matches in English, or even sounds that are so rare in English anyway that one must get creative. Say someone used "at a race" in a mnemonic for 新しい . Sure, there may be a better grouping of words for a closer *actual* pronunciation, but this selection might still actually be helpful to other users. But also, an "exact" pronunciation like "at a rash she" could be super, super difficult to write something sensible enough to be memorable. This kind of pronunciation criterion could make just about any mnemonic "objectively bad" to many, let's say, more "purist" users. Also, a user might vote it down because they find it less helpful than other users based on the way their dialect of English (or the one that they're familiar with) pronounces different English words.
What would be too "misleading" of a pronunciation? For instance, I have one where I use "time many" for たまに . Is it "objectively bad" or "misleading" because the pronunciation is more like たいまに ? I do often find I get a bit creative with pronunciation representations, usually something that keeps popping into my head whenever I encounter the word in review before I form a mnemonic, but I always include the actual pronunciation in both hiragana and romaji (for newer users who may struggle with correctly reading all hiragana at a glance, so there's less chance of misunderstanding). **Side note: I generally "hear" the correct pronunciation (especially if there's a sound recording attached to the word) in my head when I *think* of the English words I use to remember it... it's possible that many other users may do the same, rather than getting stuck on the sounds of the actual English words, as seems to be assumed.**
I would like to see the bulk of restrictions, instead, being for NSFW, offensive, etc. But even there, I'm not sure how much restriction should be required, or has/hasn't been until now. For instance, I have seen mnemonics that included "whores" ホウ and "cocaine" こく, which might bother some people more than others. And referring back to たまに , the most popular mnemonic involves *potential* non-consentual touching of a woman's body (in what could be considered a fairly intimate area), which might bother, say, women who have experienced being touched without their consent. (I know I wouldn't want someone occasionally touching MY knees... though they'd probably only make that mistake once!) But then again, it is the most popular mnemonic for the word with 68 likes, so who's to say?
I do agree with a neutral "skip" option for judging, rather than simple pass or fail. But I'm not sure how neutral votes should be counted. Though I think if a mnemonic is getting more neutrals than fails, it should probably be passed along to being visible as it may not be explicitly helpful to the majority, but it's apparently not terribly harmful and could potentially get more "likes" from a broader audience. If that's the right way to put it.
As for rewards, I think I agree that rewards may lead to abuses from less scrupulous users fishing for rewards. But I'm open to options, though I think exp would be most useful to me, personally, (at least for the time being) since I have more coins than I can spend and am still working on getting different combinations of Kaos.
That's all I can think of to contribute, for now. Thank you for letting me contribute. And I hope everyone has a great holiday!
