I read TFA, and unfortunately the research is very weak. They did not do a proper randomized study, they merely trained a classifier to figure out how good they thought a post was, and then divided up posts into pairs where their classifier thought they were the same but the feedback was different. They assume that their classifier is accurate, i.e. really reflects the goodness of a post. The rest of their research follows from this assumption.

If it had been a proper randomized study (i.e. roll a dice and up/down vote posts) I could have believed it.

Their statement seems to imply that Google Docs supports OOXML but not ODF, but the reverse is true: it supports ODF but not OOXML. I just tried the file->download as link on a document there, and one of the options is "Open Document Format (.odt)" but there is no OOXML option.

A lot of people in this discussion are suggesting that pot users may be "self-medicating" and this may explain the correlation with schizophrenia. I don't follow the science closely enough to be able to cite specific studies that contradict this, but it's unlikely for the following reason. Marijuana and the drugs that are used to treat schizophrenia have *opposite* effects on the brain. THC increases dopamine; anti-psychotic drugs decrease dopamine.

I had this problem, nearly a year ago, and as a result had to move my website from to my self-hosted website at (I explain the situation there).

What happened is I made available online a preprint of a paper that I had submitted to an Elsevier journal... this is explicitly allowed by the terms you agree to (the preprint is the draft version that you submit to the journal, before the reviewers suggest changes). Anyway, Elsevier's people submitted a DMCA request to Google, even though what I was doing was 100% allowed, and this caused Google to take down my whole homepage. Google restored my website about a week later, after I submitted a counter-notification or whatever they call it, but by that time I'd decided to move to self-hosting.

So yes, fuck Elsevier.
