Great, except people don't use stickies on a corkboard. They use push-pins. If you had custom push-pins, that would add something aesthetically. Also, if you could embed something on the corkboard, like a scribd document, that'd be very useful.

I've tried various to-do managers, notes apps, etc over the years. Everything from Google tasks to 37 signals stuff, Remember the Milk, etc, etc. Nothing has stuck for me.

Until this. Don't know what it is about it, perhaps the free form nature of the UI, but it is one of the tabs I keep open all the time with a big pile of 'to-do' items on.

My main concern is actually having it just disappear! I'd like to see the opportunity to pay for it just to know there is an account there and be more assured it will stay around.

Good stuff.

In terms of UX I'd propose one small change. Creating a new post-it by a simple click is too easy and becomes too accidental. An alternative way might be best.

Also ideally, implementing ctrl+z/y for undo/redo would be a big plus.

But good stuff.

Beats the one we hacked together over here a bit back, although we've got pins. http://corknik.com

This is cool. Realtime? Awesome.

Some thoughts:

* As others have mentioned, it's too easy to single-click accidentally and create a note.

* Pasting a URL to an image isn't discoverable. An explicit button for this on the toolbar, or one that appears when a new note is created, would be better.

* That aside, I really, really want to be able to just drag and drop images from my computer onto the page.

* As others have noted I wish I could zoom out to see more notes. The "map" is a good start but I think it should be fully zoomable.

* Chat is cool but it sort of takes you out of the experience. Try experimenting with integrating the chat into the corkboard metaphor, maybe: Instead of a pop-up in the lower-left corner, let me create post-its that are actually live chat rooms.

Anyway, this is a great start. I hope you keep improving it!

What's with having to drag to pan? Is there some reason you decided to not use native scrolling?

This is pretty amazing. Very well done!

It would be fantastic if it had a Gmaps-style zoom feature. A ZUI of a sort.

(I added this comment to the HN corkboard above but it got removed very soon afterwards!)

Edit: This was already suggested in http://news.ycombinator.com/item?id=1963075

I really liked this, until I used the shared HN one and it got really laggy / Chrome kill button came up

I like it. I don't think this will replace my stickies in OSX dashboard...but overall well done.

Very cool, I wrote something similar for my company's clients to annotate various online documents. The UI on corkboard is nicer but I have arrows,drawing tools and you can rotate the notes around so text can vertical if you want.

I like it as a demo, but if I were ever to actually use it I would want to have an account, a login, not just a URL to bookmark.

That said, don't know if I would find something like this useful if I were to try using it.

Looks awesome. I small issue though: I tried collaborating with a friend and everytime I have to hit refresh to see the changes he has made. I'm not sure if this is intended.

I love it, but it would be awesome if there was some way to persist the corkboard. As a minimum save the url in a long term cookie or something.

But definitely useful.

What is it built in?

Wow, if you step back and to the right the post it notes look real like they are really on your screen. Neat.

A timeline would be a great feature too. Being able to scroll back to my old notes and check things.

Wow I thought about making something similar, but you guys hit it out of the park!
