Warsaw at night and small change to blog

I took this photo from viewing terrace of Palace of Culture and Science (Pałac Kultury i Nauki) in my home town - Warsaw. The conditions were perfect. Blue hour light made buildings really stood out.

I also made a small change to this blog - I got rid of regular comments form and replaced it with Google+ comments. Hopefully this will help me in interaction with my readers on Google+.
