The idea of providing a summary was that many people are busy and knowing what an article is about will enable them to better allocate the small amount of time they can spend in a day on casual reading - on stuff that they are really intrigued by and feel the need to get deeper into and then they can "read articles, find out what's interesting about them for themselves, and bring the insights they've harvested to others."
I was no way suggesting that summaries are a substitue to actually reading a detailed quality piece. The point of this service is not to replace actual self-reading; but rather - Give people some idea of what the article is actually about so they can decide if they can/should invest time to read it.
Most people don't have time to do all the reading they want to do and having more info than just a clickbait headline will help them allocate their time in a more productive way.
Example this is how Vox.com is showing new articles on its "new" page:
"Big Marijuana is coming — and even legalization supporters are worried" (An activist explains why he left the movement."
The headline and snippet gives you no information what the article is about. You have to actually read 2500 words over 50 paragraphs to know what it is about, in the end you might like it, or be dissapointed, its a gamble.
But by reading a well written analysis you can have a fair idea of what you are getting into before you invest 15-20 minutes of your time into it.
Do this for 10 articles a day and 300 a month, the time you save adds up quickly.
But I get and completely respect your point about why it doesn't belong in a HN discussion. I will do this no more.
I appreciate all the users to supported this and apologize for any inconvenience caused. :)
