One of the authors, John Baez, has been blogging since before the concept existed. If you're interested in these kinds of topics his _This Week's Finds in Mathematical Physics_ is an amazing resource -- even more amazing that it's usually accessible to those of us who aren't professional physicists.

Yes, This Weeks Finds is brilliant, though not so weekly these days.

Also, on the subject of links between topology and logic - Louis Kauffman has a lot of interesting writings:
