Microsoft's Hotmail is the world's most widely used e-mail service and Microsoft is giving it a huge overhaul. Seems Microsoft is trying to keep it's competitors at bay, like Google's Gmail to name one. The update to Windows Live Hotmail is designed to remove clutter and permit it's users to interact with other web sites and applications while they are checking their email. This is what Microsoft is saying. In a blog post at windowsteamblog.com Microsoft program manager Dick Craddock said Microsoft did a study of e-mail usage for about one year while considering these changes. The new Hotmail will have one key feature that will be a "sweep" feature. It permits it's users to clear/clean out their inbox in one shot. This feature is of a single-click and will permit the user to select a single e-mail sender, or multiple senders and automatically delete every message from that sender(s). Another single click will permit users to decide which of their e-mails they want to look at (from people on their contacts list to their social networking sites or whatever). Microsoft's study showed that only 25 percent of the e-mail that people get is from their contacts list. All else tends to be related to social networks, business, or of purchases they have made online, and of course spam.
