Ask HN: Please review my bookmarking web app

http://wheatt.com

Unique value proposition: A bookmarking site with a powerful search that lets you search on tags, dates, words on page, domains, or any combination of those.

The search "today css ;design"

translates to: "Search for links added today, tagged 'design', where the page contains the word 'css'"

You can edit tags using the search

"today css ;design -design +css"

translates to: "Search for links added today, tagged 'design', where the page contains the word 'CSS', and remove the tag 'design' and add the tag 'css'"

I went live with this site about a month ago and I'm finding myself using it everyday - its turning out to be one of my least useless websites. :)

Any feedback is appreciated. Signup requires an email address and password, but a fake email address is ok. There is no validation necessary, its only for retrieving a lost password.
