However, the urls are internally still blogspot.com and also in blog's feeds. My hack for Adding post titles to Older and Newer Post links fetches the posts' urls and titles from feed and tries to change the older/newer post links' texts to post titles using the url. Local domains disturbed this, no match was found and a pseudo title was generated instead.
So I had to make a small update that changes the local domain back to .com before matching it with feed urls. Lines 34 and 41 are new, both containing this same code:
href = href.replace(/\.blogspot\.[^/]+\//, ".blogspot.com/");If you have this hack installed, I suggest you make the same update. See the whole hack with installation instructions here, source code updated: Add post titles to Older and Newer Post links.
Update June 27th 2012: new version of this hack is here, I suggest you consider using it instead of this.
