As of now you have collected 10k GBP, what are you going to do with the money with the 3k+ in unplanned additional funds? Are you going to adjust you hourly rate (not that I mind your initial "quote" wasn't that high to begin with), donate to charity, deliver more code/value, buy the Django core devs a beer? Genuinely curious. And congrats on making your goal, I love this model and I love that you had the courage to make this effort. Succeeding with this campaign publicly shows that contributing to open source software has to be an unpaid endeavor (yes I know that there are employees who get paid to contribute to open software). I wouldn't mind if more talented devs sought out crowdfunding to enhance OSS.
