How do you split your money in HB?

Default split -> Zero to Child's Play.

Almost everything to developers

Giving all to charities is the best way to get new restrictions, without developpers there are no humble bundles. So I use the default split and feel fine that way.

Most of bundles I gave all to charity. Last bundle was all to devs, Puppy Games got it all too with their last weekly bundle. I never never give a tip because I dont really care if we stop seeing bundles.

If it's a charity that solely applies to citizens of the US and that has to exist because of the lack of proper national healthcare I give nothing to charity. Mostly this is the case.

70% to developers, 20% HumbleBundle, 10% charity (Took me a while to optimize and feel good about it)
Developers need to be rewarded for their effort, and it's the games that really drive the success of all these bundles.
HumbleBundle deserves some compensation, too. Even though their default split of 15% is more than enough to cover the costs, I think that rewarding Devs and HB keeps the bundles flowing. Other Devs will be interested in joining, and HB will want to keep the gravy train rolling.
Also, charity. That's one of the objectives in these bundles, and I'm sure that it makes the Devs and HB happy to help.

It's usually 1$ or 2$ split equally between charity and tip and the remainder all to the devs... no games created=no bundles

Default for devs(except if I don't bta I take away the money for the bta devs) nothing for humble, rest for charity

95% developers 5% humble

I give something to charity depending on the charity involved. Water or support for victims of L'aquila earthquake sound ok, the others not.

34% 33% 33%

Generally I give most to charity but a little to the Humble Tip. If I REALLY like the developer I'll give money to them, which is what I did for Double Fine a while back.

Usually default split but sometimes all to charity.

Most of the time, 100% of the developers. No, I don't want to donate money to Child's Play or EFF, which are the only charities available in most of the bundles.
I do donate 50% charity 50% developers when there are available good charities, like charity: water.

Default split, mostly. Except for the WB bundle, I donated all to charity for that bundle.

I'm not really familiar with Child's Play or EFF, though. Could someone enlighten me with the good and the bad?

I'd say most of the time most of it goes to the developer, if I really like them, all of it. If I don't know them it's mostly 50 - 50 charity and Humble tip for providing this way of obtaining these games in the first place :)

around 85% to developers, 10% to to HB and whats left to charity.

I generally do an even split between the three, though for some devs I'll give more to charity and less to them.

All to charity, every time.

Same here -I care charities but I'm not planning to give sth to 'murican ones..

90-100% to charity.

All to developers

Default split.

equal parts charity/developers, and a tip to HB.
