    I don’t recommend hosting a Lemmy just for yourself. How federation currently works is it mirrors EVERYTHING. Your disk will be filled up with images you never even view and you put yourself at risk of having illegal imagery on your machine if you don’t actively keep up with which instances you must ban.

    OP’s security concern is valid. Different CAs may differ in the challenges used to verify you to be the domain owner. Using something that you could crack may lead to an attacker’s public key being certified instead.

    This could for example be the case with HTTPS verification (place a file with a specific content accessible through your URL) if the website has lacking input sanitization and/or creates files with the user’s input at an unfortunate location that collides with the challenge.

    This attack vector might be far-fetched, but there can certainly be differences between different signing authorities.

    Other than the things already mentioned, you can read analog clocks easily from great distances, as long as the handles and the face have appropriate contrast (e.g. black on white). Even with impaired vision and large distance, being able to discern the rough position of black smudges on white background is enough to tell the time. This is not possible with a digital clock, because you can’t distinguish between the digits as easily. Therefore, I’d certainly argue their much better for legibility in the back of a classroom or a lecture hall.
