When I open in Firefox, I get the error "Your browser does not support HTML5 offline database storage. Please try using Google Chrome or Safari browser for this Web App to work properly." This is a little misleading, because Firefox, Chrome, and IE 10 (but not Safari) all support IndexedDB, which is on track to be the W3C-recommended offline database storage API. Presumably this uses Web SQL Database, which is not a W3C recommendation and never will be because it attempted to standardize SQLite as the only way of implementing a database (http://www.w3.org/TR/webdatabase/).

there is a common trend of making web apps webkit-only and forgetting about everything else

Be careful, some people don't like it when that kind of thing is mentioned.

because a lot of developers are google whores

This looks very similar to the WebKit sticky note example (http://www.webkit.org/demos/sticky-notes/).

Yes but it is an extension of that by using Bookmarklets to annotate webpages instead of just one webpage.

Looks nice, but pretty rough around the edges: things like the hover on the bookmark links flicker, and when you drag notes it selects text as well.

I can't click and drag to select text, it drags the entire note. Maybe you could implement a "handle" area?

Good point

Doesn't work for me in Chrome 18.0.1025.168 m edit: on Win7 Professional

I tried your version of Chrome and it works on a Mac. Maybe you have disabled use of offline HTML database storage.

is there a way to show/hide the notes? i tried but closing them did delete em

There is a hide link in the bottom left corner of each sticky note. To unhide click on the Show Notes link or bookmark if you saved the link to your bookmark bar.
