Pavel - you should be able to find new questions via the Tag page itself from here:
[https://learn.microsoft.com/en-us/answers/tags/
Currently you can only currently browse one tag at a time, all of the filtering options on the left side of the page can help you find unanswered questions for instance.
On the right side of the page, you will find a drop down to sort the list by Updated, Created, and number of answers:
Hope this helps a bit.
