The submission process is not meant to be a "writing contest."
To clarify, the focus is on ideas, not who can write the most fluently or the most in general. It is my understanding that the program committee will not favor longer submissions over shorter submissions.
The range of word count 100 - 500 words allows for submissions of quite different lengths, which should receive the same consideration. In my opinion, if the call says 100 - 500 words, it means 100 - 500 words without preference for a longer or shorter submission.
I'm happy to clarify this on the writing tips page. The intention is to welcome folks who may not be comfortable writing in English or unfamiliar with writing these kinds of statements.
We invite non-native speakers to reach out for additional support, which we are happy to provide.
@Cscott I personally like the shorter, more structured format, which you shared. Often, having a structure like that makes it easier to put ideas into words.
