I never use general-purpose search engines if I already know which website the thing I'm looking for is on (assuming that website has it's own search functionality.) If I am looking for a wikipedia article, I go to wikipedia and search for it there. If I am looking for a tweet, I go to twitter and search for it there. If I'm searching for something on HN, then it's algolia. Search keywords in firefox make this easy.…
It’s heavily dependent on the quality of the search offered. For example — Reddit’s search functionality is terrible. I’ve found that Google is much better for searching Reddit.
Consumer advice on reddit is worthless, the subreddits about products are all run by shill-mods paid by the companies making the products. Technical information on reddit is often confidently wrong. And for general inquiries, reddit is worse than yahoo answers ever was. Most of the "I'm a [profession] and I have [experiences and opinions]" posts on reddit seem to be "creative writing" exercises, aka liars motivated by the karma system to make shit up.
