It might be good to wait until the private beta ends. During the private beta everyone can add new tags as only 1 rep is needed. It might happen that tags are removed and immediately recreated afterwards, especially those that currently have more than one question tagged with it.
After we enter the private beta 150 rep are necessary to create new tags, so even users that receive the 100 rep association-bonus are not able to immediately create tags that are considered bad on our site.
For some tags it might be OK to remove them now, eg
ice which I created. But it already happened to me that perfectly valid tags were removed. So if in doubt, please discuss the removal of a tag in a comment or ask a question here on meta.
