I noticed that we apparently have a gmail-synchronization tag, and I'm considering deleting it and retagging the ~20 questions currently using it. It seems to me that there is no need for this tag as any questions can be adequately covered by simply using gmail and sync in tandem, rather than creating a compound tag for this, which is something of an anomaly at the moment (i.e. do we create tags like this for every sync-able data feature?).
However, I'm also a little concerned that perhaps there is something unique about the way Gmail syncs it's data which I am perhaps not aware of, so I wanted to pose this question before doing anything. Is there a reasonable use for this tag that I am overlooking, which the other two do not fulfill? Should this tag be kept?
