I would like to know what your opinions on this are in general. Should we consider every visitor? In theory, I say yes... of course, we design for the users, every user. But I have heard from fellow designers that they think the people should use a higher screen resolution by now... that the times have changed. Personally I still design for 800x600... but have you made the change to a higher standard resolution?
What percentage of users should we consider? How many users should we consider?
What are your opinions on this?
