I think we have to be patient with Rosetta@home. You have to understand that this is a research project, calculating actual scientific jobs. That means that not only do they need many many scientists to create these jobs (i.e. develop a mechanism, create an initial guess structure, create the job-files etc.), but most importantly they need the manpower to evaluate and interpret the results. Otherwise the whole purpose would be lost.
Over the last couple of weeks our contribution created a large spike in their network's hashpower (as some of you already mentioned correctly). I know from experience that in the scientific world NOTHING major happens over the course of a couple of days or weeks! Enlarging a certain research project takes at least several weeks, if not months, because this depends largely on the scientific coworkers this project can pay for. I bet all these guys worked overtime the last couple of days, and still couldn't keep up. So maybe it would really be useful to have a backup project (or several ones).
That being said it would also surely help if we didn't have guys with huge amounts of small to tiny machines starting several thousand jobs, not being able to finish them, and then blocking them and crippling the whole project....
On another note: since yesterday I cannot withdraw any BBP from the main pool anymore. It sends out the email with the link, but the linked page is just a blank page and nothing happens. Also the balance on the pool account doesn't change, so that's good.
