Of course the audience this is intended for is pretty niche. Afaik there is only one other LaTeX-like library (the one I built my version upon) that achieves such a style. I don’t expect my version to blow up like bootstrap or whatever at all. Getting a maximum impact with a CSS library nowadays is extremely hard imo. I mean, we already have thousands of CSS libraries that are pretty much the same, right?

Unless your audience pays you, where's the ROI? And without an ROI, what's the point in going for maximum impact? That's just wasting time and effort that can be spent on other things: apply a stylesheet, and move on to the things that actually pay off.

I don’t see anything wrong about targeting a small audience...or doing something just because you enjoy it.

Did you have any audiences in mind? Were you thinking a one size fits all or just a larger niche?

Success of CSS themes depends a bit on fashion, so there's some risk that a popular theme will implode by getting too popular and then feel bland, overused. Or shifts in preferred styles making the theme look dated.

The LaTeX approach is sort of an anti-style. It's a uniform. I'd bet that this CSS theme will send the same message (I am an academic, and this content is for academics) for many years. A uniform should actually gain popularity as its used. Although you are correct that the reach of this theme may be limited to just academics who create websites.

lol what kind of person doubles down on a mistake/error/bias after being shown that error? do you really want me to now go and show you how many academics there are that publish papers using latex? or even publish papers in latex and publish to blogs? you probably will still claim for some reason that your initial guess was correct.

just take your L and move on.
