Problem 1): By making data open there is a risk of "information overflow", meaning that a lot of information is out there, but it has maybe little value or it is not validated (i.e. wrong). This can lead to researchers thinking an issue is solved, when actually it should be further investigated (or reproduced).
Solution 1): Information needs to be searchable in a smarter way. For this to work we need to annotate information, rated, reviewed and discussed. Over time, valuable information will gain traction (similar to large open source projects). However, this will take time and participatory efforts (which again have to be given credit to (see next problem)).
