The two are not mutually exclusive as you seem to imply. > Your users do not NEED to be educated by you. I think educating clients and users is actually crucial. For a lot of users browser was conscious choice, but there is big group that don't even know that there are different/newer browsers. First group can ignore advice but second group might benefit a lot. >It is not your business what browser they use. It absolutely is. Silly car metaphor: I'm taking my car to a service station. I expect mechanic to tell me that oil I'm using is not the optimal one. Whether or not I take his advice is my business. But informing me about substandard oil is very much his business. Also - If all of my users used modern browsers, I could save money by not spending time on ensuring my site performs well on old buggy browsers.
