As I can see, now it can be done by going to stackexchange main page (do not worry, you will see stackoverflow's questions at the end), on the right (Tag sets), click on "Interesting Tags" (or any other category you would like to), and you will get a list of those questions!
You will be able to sort the question with interesting tags by activity, newest and no answers. Best of all: you can get an rss feed at the bottom of the page of the given order of questions. Plus you can subscribe to get e-mail notifications about the news in the given tags at the "Email Updates" form with desired time interval (15 mins, 3 hours or daily).
I hope this helped.
