I took amazon links because:
1. They are most popular links to products on /r/SuggestALaptop and 80%+ mentions of laptops in Reddit comments come from this subreddit (second popular site is Newegg).
2. There is an easy access to product details via Amazon Products API
I wanted to ship it fast, so these are the reasons.
Affiliate program is a nice addition to it, but even without it I'd still collect laptop mentions this way, as it's the simplest way for me to implement such a tool.
>More mentions does not equal better.
I totally agree with it, it's only one step in laptop research, but if you don't have time or knowledge to do some more research I think it's quiete safe guess.
