@Cal I do think that occasionally tags merely add ambiguity where previously there was none. /gen /pos and /hj are unclear if you aren't familiar with them (well /hj is often unclear), while stuff like /pos and /neg either are clear from context or are clearer with /j or /s or even a smiley instead. I find a full tag like /genuine question, (or something in brackets), or just integrating the phrase into the sentence is usually way more useful and often flows better.
