Netvibes is a personalized homepage, similar to IGoogle or My Yahoo, that allows you to access your favorite services and read the news relevant to you. Nothing new, you'll say.
Despite being a French startup without too many resources, Netvibes is simply the best personalized homepage. The interface is extremely clean, you can organize your page in tabs, each module can be collapsed, you can import your feeds from an OPML file and manage them using keyboard shortcuts. Another great thing is that you can preview the content of a news by hovering over the link.
The feeds update in real time, so you'll never miss a news. Netvibes' modules take less space and look much better than Google's modules. Netvibes has a directory of modules called ecosystem, where you can find modules to add to your page and even entire tabs (collections of related modules). You can add tags and post comments for each module, to help other users and give feedback to the developers.
What can you add to Netvibes? RSS/Atom feeds, podcasts, iCal calendars, Gmail messages, notes, ToDo lists, search, weather forecast, Writely documents, bookmarks, and user-created modules.
Netvibes stores your settings in a cookie, so you can use it even when you're not registered.
