At 0.95, Nature sits at one peak of a two-peak structure — and Nature Biotechnology (0.94) sits just behind it, forming a tight cluster of Nature-branded journals before the scores step down to the broader field. The second neighborhood begins around 0.91 and runs through position 10, anchored by the National Science Foundation (0.91), Nature News & Comment (0.91), Nature Medicine (0.91), and Science Magazine (0.91).
Similarity here measures audience composition — how much the people following Nature Communications resemble those following each neighbor — not thematic overlap. The top 10 break down as seven magazines, two news publishers, and one research organization. The magazine cluster is the dominant structural fact: News from Science (0.87), WIRED Science (0.85), Nieman Reports (0.85), and The Chronicle of Higher Education (0.85) extend the magazine presence all the way to the bottom of the set. No other website — Nature Communications' own subcategory — appears in the top 10, meaning the audience shape is defined almost entirely by print-heritage science and academic publishing brands rather than by digital-native peers.
The two-peak pattern reveals an audience that bridges a specific journal family and a wider science-media ecosystem, with academic publishing magazines as the connective tissue throughout.
