I really like marginalia; even more so in this day and age where most search engines are filled to the brim with useless AI ad-infested muck. I find myself turning to marginalia search more often to find real people discussing or writing about whatever topic I'm after.
One thing I would really really love, that I didn't know I wanted until he put it in the random/explore page, is for all search results to display a screenshot of the web site that was found. It's a wonderful visual cue that helps me find stuff I've seen before; I often can picture the website I found a piece of information on, but don't have it saved anywhere. I know he's got it under the domain info, but at that point, I may as well just click the link. I think it'd be great to add it to the main search result listing.
It's a thought that has crossed my mind, and I've scratched my head quite a few times about how to present the screenshots in a way that make sense given the rest of the layout.
I also half expect some people will be confused because the screenshots I have available are only of the root document, and not the search result.
