The Washington Post have followed up their playful Facebook app Compass with the more functional newsTracker – and it’s very good indeed.

Not only can you specify which topics you want ‘fed’ to your page – but you can also include custom searches (which is why mine has no current matches – they’re very specific).

The ‘Hot News’ tag cloud is nice – but the ‘Friends’ Search Terms’ really takes advantage of the social element of Facebook technology – although it does raise possible privacy issues (Blog Friends does a similar thing very well).
