I'd highly recommend you all secure historious.com while you still can get it at a decent price (read: before you get funding, big name recognition, etc). While domain hacks are cheap and cool in the startup world, they confuse average people like our parents and neighbors.
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.
I definitely agree with this, especially since they've listed the domain for 2k. I think it's worth spending on this if this is a serious long term project.
We are a bootstrapped startup that aims to change the way you bookmark sites. In order to remain bootstrapped, we just instituted a $3/mo subscription that gives users some perks.
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:
It could be clearer whose historious you are searching. It is mentioned at the top of the page, but the text is tiny compared to what you actually interact with on the page.
I remember Kaylon's PowerMarks from years ago. I still miss the speed and ease of their tagging. I think search results, a page at a time, is a bit of a different paradigm. You might want to take a look at PowerMarks and see whether any aspects make sense to you, perhaps as an adjunct.
