It's also by a well-known website that does personal curation (not mere aggregation or mindless posting, and no shady SEO and other BS, to be worthy of the "blogspam" title). Kottke is a one-man-brand and has been at it for 2 decades...
It's still blatant blogspam, whether the person/site doing it is well-known or not.
"Noun. blogspam (Internet) promotional material posted to a weblog, often one specifically created for the purpose" -- https://en.wiktionary.org/wiki/blogspam
This definition makes it the very opposite of the post, since it's neither promotional, nor "specifically created for the purpose" of promotion.
At worst this is a personal blog site that posts interesting links and curates them. Don't know if you missed the whole 2000-2010 era, but that was a popular thing back in the day.
Sorta like a non-social HN -- where a single person selects the best bits and comments on them. Is HN "blogspam"?
Is anything that's not an original post "blogspam"?
If we were talking about automated aggregation, listicle sites, "link farms", etc, one could agree...
[1]: Is there a better term for this? HN isn't solely focused on news (and in fact has a lot of focus on olds), but the term "content aggregator" seems to imply something more like freebooting. "Social link aggregator"?
