As you know, so far, our thinking has been that it is up to each discipline to evolve. Currently, many disciplines evolve towards more openness, but this transformation is discipline-specific, and I not sure how this site can help there.
On the other hand, given the low level of activity on this site, it is hard to gauge how useful it is as it stands. Analysing the webserver logfiles might give some insights. I wanted to present a detailed evaluation of this website's usage at this year's Open Science Conference in Berlin, but my poster abstract was turned down (for the first time). So let me just throw in some basic numbers:
Total number of visits and page impressions per year (according to awstats):
|number of visits
|998,631 (+ 7,434,836 by robots)
|822,335 (+ 3,422,786 by robots)
|752,621 (+ 850,991 by robots)
So this site sees a lot of use even when it does not show any activity on the surface.
However, I understand and enjoy the fact that the community who created this site is seeking to expand its remit. Please chime in!
PS: As usual with real-world data, on closer inspection, it turns out to be unreliable. In this case I just realised that awstats received no log data from the webserver between 25 July 2019 and 2 September 2019. So in reality, usage in 2019 was higher than the table suggests.
