Feedly seems to be marketing itself as whatever interest group they think you are, because they're using NLP to highlight and categorize articles but at least for me not regarding whether they mention acquisitions, mergers, leadership changes, etc (though some of the articles my feed do) but rather whether they mention new security vulnerabilities or attacks - and I'd guess the same for many other specific niche domains.

I also saw the "new exploit" notifications. It may just be a question of feed curation, too.
