Recently I found a promising site that could become a useful resource, even though other aggregating sites (like this one) do exist already (albeit with slightly different functions).
Atheist Blogs Aggregated
has made a good start by collecting some interesting links and I suggest a quick visit for the content. Sadly though, the quirks of the excellent Blogger software have prevented the author, Joe, from getting his rss feed links and other useful features working.
I tried to e-mail him at the address that I inferred from the text at the bottom, but eventually get a permanent failure message back.
So if anyone knows Joe, please leave a comment below and let me know how to help him out.
In the meantime I will give a shout out for some great atheist blogs (apart from this one of course) that he could add to his aggregation.
A Million Gods
Steve Zara's Posterous
Martin S Pribble
Nuts and Reason
The Malcontent's Gambit
Incidentally, I used to think that Reddit was a good service to help with this, but seemingly it is now being run by a bunch of tyrants who despise anyone with an opinion taking the time to write about atheism. More on this next, in Redditing revealed - Iesvs the spoil-sport.
