Not much. Back in the day it was important to the working class, but today few people identify as working class, perhaps due to a higher social mobility in today's society. I used to celebrate the day when I was active in party politics, but I gave up that some years ago. I also think the day is slightly perverted when you see fat cat party cadre types giving speeches and talking about solidarity and the struggle of the common man.
I no longer post here after VB was sold in 2012. (See my profile page for details.)
