The day-to-day usability of LinkJam will depend on a tight browser integration. Users expect to have their bookmarks in the bookmark menu, not on some other website.
Since I think there is no way to archive integration in the browser's bookmark menu, we need another way of tight integration: what about the browser's search bar?
At least Firefox has a search box directly beside the URL field. You can add search engines of your own to the searchbox.
So I suggest to provide a way how a user can add the LinkJam site to the searchbox. Then the following should happen:
- the user enters a search phrase, like for example "planet lotus"
- search is executed at LinkJam
- if exactly one URL was found, the browser is being redirected to this URL immediately, without any user intervention.
- if more URLs were found, the standard LinkJam result page displays.
