Definitely not "same subject" if we are thinking of something as narrow as "Frontend development" but I would like many people to find a niche/style/perspective they feel at home in. Something as consistent as simonwillison.net seems good for many.
Also, my guess finding such a style/niche will take a bunch of exploration, so I think most people should probably write in a bunch of different styles and on a bunch of different things during Inkhaven to get more evidence about what they enjoy writing about the most (and which of their writing people want to read).
