1) Edits are clearly attributed. In Hackpad, editors are color coded so you never have to ask: who changed what?
2) Easy to read document history. Click the “Latest change” time at the bottom left of any pad and it will take you to a page illustrating the most recent changes.
3) Link inline to files on your Dropbox, and Access your pads offline with Dropbox.
4) Media embedding. Just paste the URL (not the embed code) for media on YouTube, Tumblr, Flickr, Google Maps to fill your pads with pictures, charts and videos–which you can watch within the pad. See Hackpad Rich Media Demo for more.
5) Code syntax highlighting. Title a pad ending in a common code extension like Hello.html or Hello.js and the body of the pad will be highlighted correctly for that language. To add inline code snippets to a pad, begin a line with four spaces and you’ll start editing in code mode. See Hackpad Code Syntax Highlighting for supported languages.
6) Easy sharing. Unlike Google Docs, you don’t have to have someone’s primary email address to share and collaborate with them. You can connect by email address, Google contacts, Facebook friends, directly through Hackpad or by simply sharing the pad’s URL–your friends don’t need to have a Hackpad account to view your pads.
7) Instant, inline linking to other pads. Just type “@” and the beginning of the title of another pad to link to that pad. If the pad doesn’t exist yet, you can highlight the text you want the new pad’s name to be, and click “Create Pad”–now that new pad exists and it is linked inline.
8) Automatically generated table of contents. Just put your section headers in bold, and Hackpad generates a table of contents on the right side of your pad. Click on the header of the section you want to jump to and save time.
9) When your pads change, you find out. As long as you are following a page (big, green button, upper right side of a pad — if it’s grey, you’re following) you will get a friendly email every time a change is made, so you don’t have to keep checking back.
10) See all the things you’ve collaborated on with someone by clicking on their name. Just click on their name on the left or avatar on the right of a pad to see a list of other pads shared between you.
11) Maybe you are just allergic to Google Docs. (Go see a doctor.)
