Clean up 'share via' menu in browser?

[voodoodaddy]

If I go to share a page from the browser I have share via:

@ delicious
@Facebook
@twitter
Plus the standard items, email, messaging, Facebook.

I don't use delicious,Facebook, or twitter. Is there some way to remove those @ items? My wife just got a Droid last night and she doesn't have that in the share menu. Perhaps its coming from other apps I have installed?
