COS is announcing important changes to the Open Science Framework (OSF).
OSF Projects—used for project collaboration, file mgmt, & storage—is being phased out as an active workspace over the next 6 months. This change does not affect persistence & accessibility of existing public projects. (🧵1/2)

Is it worth putting in all the effort needed to make your materials open if there’s a chance that no one will download them? I still think so, for two reasons:
There was a fair chunk of individual files that were never downloaded, but at the *paper* level, only 2 papers didn't have any of their materials downloaded. The median number of downloads per paper was 135.

Update: Beginning Monday Sept 14, OSF systems have been strained by significant access & download activity from automated bot traffic & crawlers. This resulted in degraded performance or inaccessibility of the platform or content, including the appearance of empty or nonfunctioning dashboards (🧵1/3)

OSF is currently down. The OSF team is aware of the issue and working to resolve. We’ll post updates as they become available.

Incredibly important work surfacing the risks and needs for improving processes for responsible data sharing.
1/ What is the prevalence of personally identifiable information (PII) in author-collected data publicly shared in the social sciences?
We audited 327 replication packages from 11 leading journals in economics, political science, and psychology
Answer: surprisingly high 🧵
