From those who've moved there in the past two years(lots too), I understand there is nothing to do in Omaha.  Is this true?
I moved here a year and a half ago. Big mistake - I can't wait to get out of here. I still haven't found anything to do. It is one of those places that is good to live if you like the midwest, have a family with 2.3 kids and want to live in the suburbs.
That's what I thought.  I bunch of RR guys to relocated the Omaha, and many stayed briefly and moved back here.

What do these people like to do?  From what I've heard there is some good momentum concerning younger people enjoying living in Omaha these days.  There are quite a few colleges and universities, including highly rated Creighton and UN Medical Center.  The Missouri River area has been developed recently and a pedestrian bridge will be added soon.  It has a world class zoo, brand new performing arts center, convention center, art museum, botanic garden and outstanding restaurants.  Its Indie music scene has become quite well known and its produced Bright Eyes and 311.  It has had 5 fortune 500 companies for many years, quite a few for its size.  Buffett money has had a positive influence on it, not because Warren gives his away, but his investors have.  Negatives IMO are not enough bike trails and public land, and weather.
I'll be real.  I've got supposadly the second/third best zoo in the country after the San Diego.  I go maybe once a year.  I do see shows at the Fox Theatre sometimes, but again rarely.  The people I know are mostly middle aged men/women who look for things to do and the ones who moved there from here aren't happy with what's available.  

Oh and the botanical garden can't even compare to the one here due to ours being like the 3rd best after one in France somewhere.  I took a college class in stl history and there's a lot here that's left over even if the rest of the city went to $hit.  I'm sure the Oracle effect isn't bad though.

My favourite story of Buffett was he was at the local country club.

I forget what prompted him, but he asked why the local club had no Jewish members.  The response came back that it had never had Jewish members.

Buffett announced that since it appeared that the club had an informal discriminatory policy, he didn't feel any need to continue to be a member of the club.

Needless to say, the club now has Jewish members ;-).

Sometimes the world can be changed, one small step at a time.
