The quickest way I've found to separate the articles that are going to be meaningless waste-of-time fluff pieces from ones that might be informative is to find the verb in the headline.

Is it something like "claims", "calls for", "praises", "criticizes", or "expects"? Fluff. If something deserving of a more concrete, direct verb had happened, the headline would have said so. Verbs like "slams" or "attacks" or "demands" are even worse; they're aggressive and enthusiastic about their content but still can't make the claim something actually happened or changed.

If the verb is preceded by "could", "might", "maybe", or similar, especially with regard to tech news, it's also probably an empty slow-news-day article, but those words aren't necessarily as hollow as the ones mentioned above. Sometimes they'll contain interesting information about the current state of things, even if they're just going to lead you on a merry speculation romp about the optimistic/horrifying future.
