Which technologies did you use? I also wonder if you plan to have an API to read all this data from my dashboard?

You are quite right about the delicious add on. We started working on some improvements to our Chrome and Firefox extensions which will hopefully make them have the key functionality of the site itself.

I think it's focused on game programming (which is good compared to html5 frameworks).

There you go: http://copyto.co/b/MTQ , used the Chrome extension to select the main content only and saved it + made the bookmark public

If you have an example site that dynamically renders a page I could try it out and show you the result

Evernote does pretty much everything thats for sure. 30 million funding should do the trick. Historious is also a nice alternative though, at least they have a stable path only on bookmarking. Anyways competition really makes services better.

There are some differences though like copyto lets you save selected parts of a page which is kind of the whole purpose behind

I guess they forgot to add it on the public site. Their email is support (at) copyto.co
