This could be useful if you have clear skies and know that a satellite is approaching . The site updates slowly so you can see the satellites move but it’s about as interesting as clock watching, paint drying etc!
There is a lot of data on this site- big lists of satellites that you can track, up to 5 at a time. If you have an interest in satellite watching this is not a bad place to start.

There’s a simple premise behind wikirage- it shows which pages are being the most edited. This could be because it’s topical, i.e. breaking news or because the pages are being furiously edited and re-edited in some kind of dispute.
Wikipedia has now passed the two million english article mark which is a phenomenal achievement in six years. So I expect one or two tracking sites like this to appear as people create new ways to study this.
