There are a number of sites on the Web that list translation weblogs.
The Polyglot blog has just published its updated long list. What language the blogs are in is not always clear, but it’s easy to click through and check.
Recently, mygengo.com has been adding a page for each of a number of translation weblogs. Here’s the list, and here is the page for Transblawg. This list might be an easier place to start, as it’s growing but not yet as long as the Polyglot one.
As far as my blog is concerned, they have definitely made the effort of reading it and actually point out that a knowledge of German would be useful (because I don’t translate all the German I quote and some of my links are German). They also have tags like ‘German’ so one can narrow down the list, and they supply an RSS link, for example, for each blog.
