Robin Good: Protopage is a free web service which allows you to easily monitor any keyword, hashtag, topic, RSS feed (and OPML files too) or web site on a custom, personalized private web page.
You can add as many "search" and monitoring widgets to your page and create multiple tabs to monitor and check different topics without creating excessive clutter.
Widgets can contain dozen of different information objects besides searches, including video feeds, news, audio podcasts, bookmarks, maps, and a lot more. Check all the widgets you can add here: http://i.imgur.com/BseEu.jpg
