Back in January 2009, I posted the  2009 Ultra Mega conference list of about 80 upcoming conferences that interested me in the social media, tech. feminism and community areas.
That list went through about April 09.

I've just pulled together another list, which is Part 2 of the 2009 Ultra Mega conference list. This time, it's a bit broader (online news and sustainability are bigger themes), and there's a PDF file at the end that you can download.

Here's the list.  Conferences I am attending are in bold.
