Thanks @elear for starting a discussion. I can see people have been expressing themselves openly and this is a good thing. There are lots of arguments I agree with.

First of all, let's talk about the questionnaire:
We have been brainstorming and discussing the questionnaire issue for months on Discord, but I can't say I am happy with the proposed draft. Why should we pay so much attention on the presentation post? 2 questions (#1 concerning presentation/formatting and #2 concerning writing style/language/engagement - of course the basic project details should all be there in order to consider the post complete). We could also skip this question or just narrow down the options to a) basic and b) well-written, therefore the translator who wants to get these extra points will know what to do.

Linear rewards like @alexs1320 has also mentioned. This is an argument I do agree with, when we have a 1100-word and a 1600-word contribution, we can't reward them the same (considering they are of the same difficulty level and semantic accuracy).

Defining more clearly the number of mistakes as well as the type of mistakes (semantics, spelling, typo) is also important as these define the quality of the text the LM receives.

Pre-defining difficulty levels of all projects is also important and leads to a common agreement, leaving no room for unfair scorings among all language groups (as there have been projects rated of "high difficulty" by some LMs while others rated them as of "average" or "low").

From what I (and others here) see, we are trying to "cut down on" points from very good translations if this questionnaire is implemented. This will most likely un-motivate people. We want to keep balances and make everyone happy (as long as this is feasible). "Punishing" good contributions because they are good I don't think will get us anywhere. Instead, we should try to help "mediocrity" get better. The feedback from the LM is supposed to help a translator become better and better, why should score lower excellent contributions? Just because the category's VP % is limited? And why not just drop the score/upvote % ratio a little?

Now regarding the category as a whole:
IMHO Translations have been expanding too rapidly. We have so many people on board in a few months, I doubt this will be sustainable in the long run and I am not the only one to point this out (@scienceangel has stated the same).

@rosatravels has tried to make the "translations community" more engaging and active, she has made very beautiful posts featuring LMs and translators, but let's be honest, translation posts are not "engagement material", their target group (here on Steemit) is very limited. We try to make our posts more enjoyable and give them a more personal tone or explain a few things about the project we are working on or some tools and features it offers, but nobody will read what we write in there (nobody else other than the LM who reviews it).
