I just miss organization. Everything feels like a mess now. Content is either in an endless scroll or it's only accessible through a search box and you have absolutely no idea whether the site doesn't have the content you wanted or if you just failed to use the correct terms. Increased reliance on CDNs and cross-site content has simultaneously made web pages expire faster than ever and made them harder to archive.
Multimedia is also a shadow of what it once was. Twenty years ago it was common for material to be presented in a way that integrated text, sound, pictures, and video together in an easily navigable way. A page on, say, Lewis and Clark would offer you an audio introduction, an interactive map that brought up text journal entries for clickable points of interest, and relevant pictures. Now your only option is a web page with embedded pictures which may as well be a paper encyclopedia entry, or a video that may or may not offer you any useful way to navigate it aside from jumping around at random and most certainly doesn't give you rich annotations throughout.
