I made a simple bookmarklet to make reading/sharing news easier.
Everything is just 2 clicks away:
1. find archive.today or archive.org links
2. post to HN, Reddit or Twitter
3. find the current page on HN, Reddit or Twitter
Just go to newsyup.com. It's a bookmark, so no extension, no installation, no registration.
I think what you are doing can be implemented entirely in client side javascript. You seems to be doing some server side templating at least, which feels like unnecessary and can become a bottleneck.
