So... I'm looking at this this, and theoretically I'm qualified to write articles about these topics. I don't actually see how any of these topics are something that would be beneficial to have an article about, though. Writing game stories really isn't different than other kinds of writing, especially screenwriting and comic script writing. There's an absolute flood of how-to-write books for beginners out there. And IMNSHO a writer who still qualifies as a beginner has no business publishing their writing, in a game or anywhere else. Now, interactive fiction is kind of unique to games, but it's not even on this list, nor are any of the more advanced topics in fiction writing that there's an actual lack of existing books about.
The list is just some potential ideas, if you feel there are more advanced subjects that would be appropriate and that you're qualified to cover by all means submit an article about those instead! I'd love to see some articles on how to approach interactive fiction or the interactive dialogue presented in some games, as well as any other advanced topics you feel aren't well covered (or covered at all) elsewhere!
To more directly answer your question about writing an article or articles covering these more basic topics, I think the benefits would be:
- Making that knowledge more readily available -- a lot of would-be writers don't know what topics they should be studying or where/how to go about doing so. Much like the basic art article Prinz Eugn has asked for input on the topic list for, beginners might find it beneficial to read an article that briefly touched on what areas of study could be useful even if only a cursory summary was provided along with links to further learning material. It's all well and good to suggest that only properly trained writers should be publishing their writing, but programmers/artists/lay-people are inevitably going to continue to publish their works as well, and by making those people more aware of the different techniques and resources available to them perhaps we can help them to produce higher quality work.
- You could specifically cover subjects from a "game development" perspective.
