mooredsThe death of east London's most radical bookshop

> Since opening, the Scarlett Letters hadn’t made a month-by-month profit, but had been kept afloat by savings and a monthly donation of £10,000 from an anonymous “angel investor”.
Sounds like it wasn't so much a business as a piece of performance art.
I understand the dynamics of book stores and see how you could carry something like this for a long time with a not-crazy amount of money but what weirds me out are the people involved in the project who get mad at the "angel investors".
