In the Blogger Help Group I reported a long-standing bug
that has existed ever since Google acquired Blogger. A direct links to a Blogger post has a unique numerical identifier. The direct link to my first post of the year is:http://alankhenderson.blogspot.com/2009_01_01_archive.html#8364007883149853217
However, since the Google acquisition the direct links have been double-inserting the unique identifier, like this:http://alankhenderson.blogspot.com/2009_01_01_archive.html#8364007883149853217#8364007883149853217
Click that faulty link and it simply takes you to the top of the blog, not to the nonexistent URL.
I can't get a reply from the Blogger Help Group, and Blogger itself has no technical support contact info.
