I am interested in making something like delicious.com, but that I would run on my own server. It needs to:
- Create a screenshot of the page
- Download the page as an archive (with all assets)
- Auto tagging (custom tags work too)
- Sharing (via twitter, facebook, or importing into other bookmarking stuffs)
- RSS everywhere
Open sourcing it and making it a cinch to run on Heroku would be great, so that anyone could run their own version of it.
