1. Seeing a list of people associated with a product is kind of useful, but I specifically want to know what their role was / what they did, vs. just a generic quote.
2. I like the idea of having versions under a larger high-level product (like Mac → Apple Macintosh 128K) but this doesn't seem to be expressed in the navigation anywhere when you're on a specific version. There should be some form of breadcrumbing / indicating the parent.
3. I'd reconsider the tabs as distinct pages vs. a single page, Wikipedia style where the tabs just act as anchors. Possibly use an accordion pattern with a preview for each section. Right now I have to click through 8 different tabs to see if there's possibly content which is usually pretty sparse.
4. Product pages should look distinct from the homepage. The hero section with the tagline / search field is really prominent (and autofocused) when you're looking at a specific product / version. The main focus should be the product title, and the header should be secondary.
5. Not crazy about the quotes as the lead-in for the product pages. It feels like it should be a succinct summary of what the product was. Information like release date, size of team, etc... should be above the fold. I think Wikipedia is again instructive.
6. As a more meta comment, lack of data is definitely an issue and at the same it seems tough to encourage people to contribute data to a (sorry) unknown entity. I tried to edit an article to see how the data's being captured but didn't want to create an account — are you familiar with Wikidata, RDF, Linked Data, etc...? If you can't find this data already in a structured way, I've spent some time parsing wikitext somewhat successfully and if you look at e.g. the Credits section https://en.wikipedia.org/wiki/Macintosh_128K#Credits you might be able to bootstrap some data (or at least provide draft pages that someone can then vet / fill out).
7. From what I understand, scraping LinkedIn is pretty challenging, but could you gather data from there / cross-reference to infer who worked on what products? LinkedIn specifically has "Projects" and "Creators", but I don't know what its adoption is like. Basically vs. just expecting me (the general user) to crowdsource this for you, what initial work have you put in.
