Competitive coding contests are in a way similar to chess or olympiads and it is a sport in itself.
For all the years I have spent and observed on topcoder, Google Code Jam and others I haven't seen a lot of women coders reaching the top, not even from Russia. So what these girls are achieving is a big deal and should inspire many. It is a little disappointing to see comments like they didn't crush because they didn't get the first prize. Consistent winning of multiple contests is definitely something and they are doing it pretty well.
