I just heard this news today - what a bummer. There was over 109 BTC in the wallet until just recently. Obviously you've made your decision, but it's too bad it couldn't continue until the wallet ran dry. It was only this year that I started to pitch Bitcoin 100 to local non-profits, only to discover it was basically over.
It's now going to be a lot harder to overcome objections to non-profits accepting bitcoin. "Why should we jump through all these hoops?" would get wiped away as an objection if a $1,000 donation was in the offering.
Would have been cool if this could continue, but thank you for doing it for as long as you did and as successfully as you did.

Thank you for your sentiment, Ian, with apologies for Bitcoin 100 not running a fuller course that you've envisioned, but as you can see we no longer had the bitcoin100.org domain damain, thus no site, let alone not having an official charter (virtually a mute issue, but just the same), etc. Most everybody agrees that Bitcoin 100 was instrumental in one capacity or another in advancing Bitcoin proper via the NPO space where mostly needy charities were endowed. I'd say that BitPay's Tony Gallippi saw the potential using bitcoins in the NPO space thanks to more than in part (my assessment) of Bitcoin 100's success, thus his sister starting up BitGive, in turn they being instrumental in The Water Project accepting bitcoins which we endowed, and hopefully will again come Christmas along with Jason King's Unsung with projected remaining funds in our coffer, so that come December 26, 2016, we'll be bone dry.
