This is a really cool idea!

edit: feature/request

Scenario, if I save a link from HackerNews, I like to save the submission of it as well. I wonder if I send a HackerNews link to forlater.email; it can parse the article and remind me I got it from HackerNews.

For example, I'd submit "https://news.ycombinator.com/item?id=31852384" and in the email, it'd contain:

1. HackerNews link (so i can review the comments as well)

2. Original article link and content

food for thought, but love your product idea
