I just noticed that lxml reached rank 5 on Google when you look for "elementtree", just after two links for ElementTree itself and another two for the Python standard library, so it's more of a rank 3!
Yahoo sees us within the top 10.
MSN at least underlines the ElementTree compatibility of lxml in its Top-5
although it doesn't find our homepage is good enough for rank 1 when you ask it for "lxml".
But then again, Microsoft isn't the first place to ask for OpenSource software anyway...
