I have always designed so every resolution can view my website but I hate designing with tables using percentages so have always kept everything withing 600 pixels. Hence my sites have always looked far too small in higher resolutions.
Poll: Should I always design with everyone in mind or should I go with sitepoint and make my site only accesible for people running a resolutions of 800x600 or above
I predict that most of my visitors with be viewing in a high resolution anyway but there will always be the odd few who will go for the more traditional 640x480.
Thanks for your replies, in the past I have always done the same as you two and designed with a centred table that every resolution will see. The reason I posted this was because it doesn't give you much space to work with and I noticed that sitepoint made the choice to only fit for resolutions of 800x600 and above.
Keep in mind the research that has been done about the ability of the human eye to scan across a long-lin-width. If getting across to the user is your aim, make it easy for them to read. Flexible screen text can be brutal to read if you don't limit the column width.
