The lag tag (on 30 questions) seems awful. In common parlance "lag" is a catch-all term for poor performance; attributable to myriad things. Many of the questions it's on have a network bent, but several seem to be just about a local slowdown (graphics card/CPU overload, slow input)
Incorporating badp's suggestion:
- remove synonym from ping to lag
- create synonym from ping to latency
- rename lag to latency
- create synonym from lag to technical-issues (the new dumpster)
- manually go through latency questions and retag the non-network related ones (8-10 of 30) to performance or technical-issues as appropriate.
