Historious just got public pages and subscriptions
historio.us
historio.us
The potential for confusion is one of the reasons that Yahoo forked over big bucks to buy delicious.com and redirect del.icio.us there. Even if you wanted to keep your domain hack, you could always point the .com version to your domain hack. It sure beats letting someone else show ads and confuse customers to where they think you've gone out of business.
EDIT: We have historious.net and .org now and they are pointing to historio.us. Thanks again for the nudge!
We also launched public user pages where you can share your bookmarks and give users the link so they can search your bookmarked items. This is my page, for example:
http://stavros.historio.us/search/
We would, once more, appreciate your feedback!
Best wishes! Giving your site a go, myself.
