comment Is there a usability reason for centering a website's content area on a page?
@PhilipSeyfi, I agree that it shouldn't stretch text to 30". But it shouldn't also crop the site if you only gave it 800px width. Is it possible to get both of these correct? (Note we are talking window size, not screen resolution.) Meanwhile, my question remains: when someone goes full-screen with a browser on a 30" monitor, what is he trying to accomplish?

comment Do columns of text hurt readability on websites?
Having to scroll back up to start the second column is pretty bad usability. Multi-column works on paper because you can see the whole page. (And the fonts may tend to be smaller, lowering the practical limit on line width.)

@PhilipSeyfi, a responsive design would try to use all that space, no? What I'm really trying to understand is the use case of a 30"-wide browser window. What do you do with all that space that it's worth going full-screen?

You read full-width text on a 30" monitor? Ouch! How do you keep the whole line in focus and not "miss" when going to the next line? (If your answer is "nobody reads lines that wide", why are you browsing full-width? What am I missing?)

There's also a moment of confusion/annoyance when someone with a smaller browser window (or screen) visits a center-aligned web site that isn't liquid. If you have to horizontally scroll in order to read all the content, there's a problem. So "centered in the space given" is good; "centered in the space we decided is the right width for the site" isn't.

comment Why are Inverted Colors considered an accessibility feature?
I'm one of those vision-challenged people, and @RogerAttrill and Christian are spot-on WRT my experience. The bombardment from a background full of light-emitting white pixels makes the black text harder to read, particularly with extended usage. But I can read for hours on my Kindle (e-ink) with no problems; paper (real or simulated) is different. BTW, the Mac "solution" to this problem is completely useless to me; pixel inversion does too much collateral damage (like photos). On Windows I can define a color scheme. (I use my Mac for shorter periods of time; work machine is Windows.)

comment Re-plotting items on a map
(1) What does (left-)click do? That's a common idiom for "select" in other applications, so if you want to break it down as select + relocate, left-click seems more natural than right-click. (2) The answer to this will be affected by the properties of your map, so can you tell us more about that? How dense do movable items tend to be? How often do people pan/zoom vs just working with a static map? What other mouse-based gestures do you already support? (You mentioned pan and a right-click menu; anything else?) Is everything mouse-based or do they also use the keyboard for anything?

comment How can I measure why users never return to a web app?
@BartoszRakowski, the original title was way too broad and vague, so the question needed to be focused. If that's not the dimension along which Tara wanted to focus it, she can always edit.

comment How can I show marking state (for individual data values) in aggregate representations?
With multiple source of marking and not-necessarily-known semantics of marks, that seems like it could explode very quickly. Instead of trying to call out every collection of marks I'm trying to signal to the user "hey, two of those and one of these are marked; if you care you might want to check that out". What presentation signals that short of "Inbox (89, 2 red, 1 blue, 3 green)"?

comment Is it good to limit the user to a set number of selectable font / background colors?
I'm suggesting that you'll always miss something because users are complicated. The common approach of providing, say, 16 pre-chosen colors and a color wheel for fine-tuning seems to work well; choose those 16 colors well and most of your users will just take those, but if somebody does need more control it's available. If you're building an application from scratch and the color wheel adds too much complexity that's different, but in a case where you already have that, why not continue to make it available? Where's the harm?
