@Askopenscience could do this. But note that the Open Access Tracking Project is already doing it. For example, see the OATP tag libraries for oa.jobs, oa.events, and oa.policies. OATP is nonprofit, crowd-sourced, runs on open-source software, and welcomes new contributors. We'd also be happy to talk with @Askopenscience about possibilities for collaboration.
Ask Open Science used to be called Open Science Q&A but we changed the name when we registered the domain ask-open-science.org. Everything else stays the same: We are still hosted by Bielefeld University.
