I used Blueprint a long time ago, one of the earliest versions, and had a lot of trouble with it. Like any abstraction it's only flexible to a point and I feel like CSS being a presentation language means that that flexibility is hindered and your ability to recover weakened as compared to frameworks in turing complete languages. That being said I haven't used Blueprint in a long time and I've used CSS longer than I've used any language besides HTML. I'm probably not so much in the intended audience.
