* [tag:conversion] should be synonymous with [tag:format-conversion]

* [tag:convert] should be deleted or made a synonym of [tag:conversion]


* Should [tag:video-conversion] be a separate tag, or should this be rolled into 'conversion/format-conversion' as well? 

* A related tag, [tag:file-format], seems like it might be able to stand on its own.  

Seth's comment pointing out the weakness of 'file-format' seems valid. It would have to be more clearly defined. Could be related to questions on particular file formats -- e.g., tarj, gzip, 7zip, iso, cue, xml, csv -- that are not conversion questions, but use or content or programamtic interaction questions. Which isn't to say there's not a better overarching tag for those, or that the tag is necessary.
