BlogHer Conference

I keep hearing about this nifty conference that a couple of different women whose blogs I follow attended recently in Chicago. Is it in Chicago every year?

I'll keep this simple I WANT TO GO NEXT YEAR! I don't know how it works...I wonder if you need to have some sort of 'special' blog in order to go? Some people have VERY involved blogs. They overwhelm and confuse me. I wouldn't even know how to keep one of these VERY involved blogs. I'm lucky if the pictures I post are in chronological order. No matter- how do I get invited/tickets to this event next year? It looks like SO much fun and a great way to meet lots of new people.

If anyone has any info on this, let me know!
