Xobni
Xobni (Inbox spelled backwards) is a neat little tool that leverages data / connections (some would call it spam) that all of us have in our inboxes and turns that into useful information. (This really belongs in a blog on personal productivity but it thought it may be interesting to people here that are drowning in email.)

Some of the features in Xobni (such as search) can be found in either Google Desktop or in Microsoft search (which is now integrated with Outlook 2007), but I really like the insights that it provides. What especially caught my eye was the graph that shows when your contacts send emails, the ‘email deficit’ between you and your contact and the ability to quickly find attachments. Can’t wait to try this out. Thanks to Don Dodge for pointing this out.
