Will this piss big g man off ?

Hey Guys

IV got a sports site thats about 6 months old and its doing quite well in the rankings. I have a plugin that changes my tags into another post and i have been posting lots of tags which are showing before the content on my pages (half the page is tags).

Will this harm me in the long run ? if i hide the tags on my site will that harm me ?

This probably is not a good idea. Tag pages have a tendency to create duplicate content if you are indexing and following it.
