I am meeting Mr. Excel aka Bill Jelen tomorrow. What do you want to ask him? (book giveaway too):
One of the beautiful things about working on internet is you know so much about people even before you meet them first time. I think I first heard about Mr. Excel in 2006, when I started my career as business analyst. I landed on mrexcel.com while searching for something related to doing cluster analysis using Excel. In a way, mrexcel.com inspired me to share my thoughts and techniques on Chandoo.org.
So it wont be an understatement when I say, I feel like a kid in candy store knowing that Bill Jelen aka Mr. Excel is just a few miles away from where I live. Since Rob Collie and Bill are good friends, I asked Rob if we 3 can meet for dinner. And Bill said yes. 
I am meeting Bill for dinner on Friday and Rob, Bill & I will be discussing spreadsheets, technology, share our experiences and bump ideas off each other.

So what is in it for you?

But I want you to be part of this too. So go ahead and  post your questions to Bill in comments. I am going to ask him all these and feature in an interview style post (with a photo Bill and me of course) next week. You can ask anything related to Excel, Bill’s life, mrexcel.com or general stuff. Hilarious, whacky, outright fun questions are welcome.

Bonus: Signed copy of Bill’s book

I will pick one random commenter (on this post) and send her / him a signed copy of one of Bill’s books. I am trying to get Excel 2013 in-depth, but the title may change if we cant get hold of a copy in time.
The book will be autographed by Bill Jelen, Rob Collie and yours truly.
I am sure as a Chandoo.org visitor, you know the value of this. Just in case you don’t, here we go: You might be able to sell it for millions if the world becomes spreadsheet oriented as we approach singularity
