Here’s the short scoop on two new interesting Digg-related tools.

One is an unofficial recommendation engine for Digg called Digg Filter. It’s really simple: enter your username and you will get a bunch of stories that are “recommended” for you. I’m not a big fan of automated recommendation engines but this seems to be a much-sought feature, and one that Digg plans to implement soon, so Digg Filter can be seen as a “preview” of this upcoming option. Read Muhammad Saleem’s interview with the author over at RWW.

The other tool I’ve dug up in Digg’s upcoming stories is called Digg Explorer, and it offers a neat visual representation of certain Digg statistics: often used words, popular topics and subtopics, most active dates, etc. It’s all based on the last 500 front paged Digg stories, so don’t expect data from a year ago, but it’s still a great reference, with the added bonus of looking really nice.
