I'm not quite sure I understand why you wouldn't want to use an add-on. I can certainly see that the flip side is undesirable. Do you think it makes sense for hacker news to solve this same issue (read it later) when there are many external options to solve the issue? If your answer to this is yes, would you also support adding tweet this story buttons? What about share on Facebook, email me a copy, copy to slack, print to google print, etc. buttons? What about friending users, following them, private messaging? Should hacker news allow images in stories next? If it adds images, then perhaps advertising would be ok?
What are some of the reasons that you read hacker news beyond the particular stories? How do you find the interface? Is it uncluttered? Does it get in the way of the content at all?
In my opinion hacker news is fine as it is, though I mostly hit it via http://hckrnews.com instead of the main site.
Safari has a feature called "Reading List" that does exactly this, but for the entire Internet in a generic way instead of only as some specific feature on this one website tied to an account.
Is anyone aware of a tool that will allow me to search through my browsing history? I'm constantly reading things, forgetting where I read them, and then wanting to remember what it was I reading yesterday, the day before, or earlier.
http://fetching.io/ is a tool I once used but had issues when we did a local or cloud option with no way to pull my cloud data to the local while also not being willing to pay for cloud one out of beta. The dev seems like a good guy and if I were to try it again I would use it.
