My new microblog plugin reached RC2 and works so far. Give it a try: http://board.s9y.org/viewtopic.php?f=10 ... 979#p85979
@jdwarren: Huh, alot of stuff, maybe you schould open a new thread for this feature request. Perhaps someone wants to port this plugin or parts of it to S9Y.
Edit: Found the bug in IE6, it was just a miscoded JS-File.
