Nitrile gloves are quite useless against many common substances, including acetone, esters, acetic acid, and everything else with "acet" in the name. Aside from a few cases where nitrile works and others don't (some hydrocarbons, among others), there's usually something more protective.
For non chemists just working with standard commercial stuff(Epoxy, UV resin, grocery store cleaning chemicals, and that's about it), various sites and ads give the impression nitrile is "The good default thing you should use"....
