In the context of today, a thought on whether forums like this can help people distinguish effective treatments.
Maybe they can. As it turned out,
@Hip's non-blinded, non-ethics approved, non-funded roundup of people who claimed to have tried rituximab may have given us the best heads-up into the prospects of Phase III. (Hip found far more non-responders than responders.) Hip had nothing to sell, no prizes or promotions to win, and only sought the truth.
It lends some credence to the Julie Rehmeyer school of exploiting the non-structured information you can find online, rather than only waiting for the formal and highly structured information that emanates from randomised controlled trials. RCTs are great quality evidence but awfully rare. You can do science starting with non-structured information. You just have to be careful.
I've been pondering
@Jesse2233 's discovery of a large group of people with an improvement from mhbot. On the one hand, it's not formal science. On the other hand, it is evidence of a kind. Today's result makes me more inclined toward carefully placing belief in patient self-reports, (if they're numerous and dispersed enough and you can find reason to believe they're not affected by a common error such as a charismatic clinician or LP style brainwashing process .)
