Start.me is a free service for organizing all of your favorite sites, RSS feeds, and social networks in one place. The easiest way to describe Start.me is to call it an iGoogle replacement. On Start.me you can create as many start pages or homepages as you like. On each page you can include widgets for RSS feeds, bookmarks, feeds from social networks, and you can include calendars from your Google Account. Start.me offers a browser bookmarklet that you can use to add content to your start pages at any time.
The first time that you use Start.me you will be greeted by a default start page. To remove a widget from the default page just click on the edit option in the upper-right corner of the widget. From that same edit menu you can also remove an element of a widget without removing the entire widget. If you would like to add a widget use the "add" menu in the top-left corner of the page. The "add" menu is the same menu that provides the option to create additional start pages within your account.
Applications for Education
I have never been a big user of start pages, but I know that a lot teachers like to use them as a place to organize the resources they use with students on a regular basis. The appeal of Start.me for those teachers could be the option to create multiple start pages. By using that option teachers could create a different start page for each of the courses that they teach.
