Only show questions without some set of tags?
Right now, physics overflow is dominated by mathematical physics, string theory, quantum field theory etc. This is very fine with me (and it tracks the early usage pattern of arXiv back in the 90s). However, for someone like me (nanophysics/quantum optics), it would be very good if I could simply hide all the questions that contain tags like "string theory" etc. It would be even better if I could somehow set this in my preferences. And it would be best for the community, if there were a few short-cut links at the top of the recent Q&A page that automatically switch to some particular topics (as identified by the presence/absence of a set of tags). Simply having a broad category like "Theoretical Physics" is unfortunately not enough.
