For future suggestions, make a separate post so we can keep track of how well we are doing with tags, as well as facilitating discussion on a specific tag. Thanks
I don't have enough reputation to suggest or vote on tag synonyms, but I've noticed some possible synonyms. I already posted one suggestion in a separate question about whether I should suggest them here on meta, but I thought it would be useful to have a post just for suggested synonyms.
I'm not sure what an appropriate format is, but the synonyms page lists them in a table with master tag to the left of the synonym with a left facing arrow. Therefore, I will post my suggestions in the answers using the format "master < synonym"
