It seems that in a system like del.icio.us which is very open social practice will reinforce some standard way of dealing with things like synonyms. maybe it can be expected that people will eventually use the most common words in the system for tagging if they want to make full use of the social benefits that the system offers.
if on the other hand people use del.icio.us and the like only for their personal benefit or for a small group then there is nothing wrong with using different words than some other subgroup.
