I know that the Matrix differs from edition to edition of Shadowrun. It still feels quite redundant having a question tagged "shadowrun-sr4 sr4-matrix". Shouldn't all the matrix tags be merged? The question would be tagged "shadowrun-sr4 sr-matrix" or something similar, so the system is still identified.
Is it practical being so specific? Which case would be more common, someone looking for matrix questions without caring edition, or someone looking for specific matrix edition questions?
