it sounds like it could be cool! you’ve already shared it around so federation won’t be a problem

although it’s a bit similar to !retronet@lemmy.sdf.org and !oldweb@retrolemmy.com and !oldweb@lemmy.ml

Do you have any sources for old websites that can be used to post here? or any other kinds of resources?

your custom CSS is a little hard to read, maybe needs a slightly bigger font size, especially for the post titles, or maybe just more letter-spacing

I think just this is enough

.post_teaser_title_a {
    letter-spacing: 1px;
}

Just added it to Lemmy Federate; that should help with visibility.
