Hi Alex!

I don't think empty title attributes are very reasonable.

But they help resolving a bug in IE<7. If no title-attribute is given, IE<7 displays the alt-attribute, which is really stupid.

Furthermore I do not make major efforts for IE 6 anymore.

Come on, two lines of code - I wouldn't call that a major effort. I'm running a forum for a global audience and according to my server logs still 60% of user-agents are IE6 (or lower).
