If I run twiogle and it puts a comment for me on a post tagged with "art", then anywhere the word "art" appears in the comment, it is replaced with the first letter: "a".
For example, comment: "Call for articles and artworks - Art in the age of pervasive data http://bit.ly/9NnkmK" is listed as "Call for aicles and aworks - A in the age of pervasive data http://bit.ly/9NnkmK".
How weird.
