links on foruns/signatures counts for google page ranks?

links on forums, posts signatures, don't counts for google page ranks?
because I search in google for 'Find web pages from the site pjdc.blogspot.com' there is only one entry return, a link from another blogs. None blog comments, entries on blogs catalog, foruns signatures are returned.
google indetifies this kind of links and ignores it ?

According to a study performed by Digital Point (I cannot remember the URL), links in forum signatures are filtered out by Googlebot.
