KrumIr does social bookmarking with Twitter integration

As Twitter's popularity continues to grow, so do the number of applications that tap into their API. If you use Twitter to share web pages that you find interesting with your followers, you may want to check out KrumIr.

Apart from offering the usual tagging options when you add a new bookmark, KrumIr can tweet your new link. It's not submitted automatically, so you'll be able to add a message to the truncated KrumIr URL. When one of your followers clicks the link, the page will display with a handy header that allows them to quickly retweet your message.

Since you add links to KrumIr with bookmarklets, it will work with any browser - including the iPhone, iPod Touch, and G1. Three different options are provided: bookmark, bookmark and tweet, and bookmark/tweet/thumbnail. KrumIr also allows you to create private bookmarks for sites you don't feel the need to share.
