Shadow To Light blog is one of my favorite blogs that covers the topic of atheism. It is the only Christian blog that I am aware of that almost exclusively focuses on the topic of atheism and posts regularly. And it is well-written and well-researched.
The Shadow To Light blog may be the only theistic blog in the world to regularly post on atheism (The blog Atheism Analyzed has diversified into covering leftist politics as well).
I spoke to a Christian apologists who mentioned the Shadow To Light blog and he had a very favorable opinion of the blog.
Many Europeans seem apathetic about the atheism vs. Christianity issue and outspoken atheists are a tiny squeak of the population in most of the non-European countries of the world.
The three main battlefronts related to atheism are: Europe, China and the United States (admittedly atheists are a very small percentage of the American population. According to Pew Research, in 2012 2.4% of American adults say they are atheists). The 21st century is not going to be kind to the atheist movement in Europe and China (see: Desecularization in Europe and Asian atheism).
Is there a Christian blog on atheism in Asia that posts regularly? Maybe, but I doubt it exists in China given Chinese censorship of the internet.
Are there any theistic blogs on atheism in Islamic countries? I doubt it. First, atheists are likely a squeak in the population of all Islamic societies. Second, the Islamic countries mainly oppose atheism via social ostracism, vigilante and family violence against atheists (Apostates to Islam are often killed in Islamic countries) and laws against atheism (A Saudi outspoken atheists was recently imprisoned, fined and sentenced to 2,000 lashes to be given over period of time).
