I find that looking into anecdotal evidence online is really tedious as I don't care about most content of the experience reports. I just care about: does this substance help with X? what are the side effects?
I would love to be able to just search on a database for all the things that help with X ranked by the % of users with X that report an effect, for example. I am sure many of you sometimes want to look quickly for other statistics of a different nature: does it work for people your age, or your gender, or with your conditions, or when combined with something else.
Why isn't there a central resource where people can report their personal background (anonymously) and experiences in a standardized form (not in a long story format), enabling you to make custom queries?
To start with it would just be a website where you submit your background (Age: <0-200>, Gender: <male/female>, Health conditions:...), intervention (Piracetam, dosage <...>, for <time period>), and add categories (e.g. Analytical ability change: <much improved/.../.../much declined>, Total sleep time: <number>, Subjective well being: <1-10> etc). There is no need to define all the categories as the users add them iteratively, making this a relatively simple undertaking.
