Hi there,
I'm on my laptop now. I miss the old mobile site
Seriously, I had a look at the new MN mobile site on my DD's ipod touch, safari browser (which is a year old, can't tell you what version) and it looks quite different, so I do see why you are having issues making it work for everyone.
So, on the ipod touch, the screen is still very, very glary and white compared to what I am seeing on my Nokia Lumia now; but the font is bigger and more legible (and MN font on the i-touch is more like what I am seeing on the Guardian website on my Nokia Lumia).
So, I just looked at the Guardian website on my DD's i-touch and it is really glary on there too; in fact, I don't think I could read that either for long.
So, I have just turned down the brightness on the i-touch to about half what it was (DD will love me), so I can actually look at it. (Clearly my issue, that one)
Going back to the MN website, I now have (on the i-touch) a dimmer screen and legible font; but I am still struggling with it. I noticed somewhere on the thread that you suggest that you are looking at breaking up the text. I think that is a good idea, but the other point on the Guardian site (sorry, not comparing, just that you mentioned it earlier that I read it), is that the fonts are different sizes to highlight different things - so the headlines are different from the synopsis of the story which is different from the story itself. And the same on the BTL posts, you have blue bold for the poster name, then underneath small grey writing and then kind of in-betweeny black writing. On the right hand side, you have got the recommend button and on the left the poster's picture.
On MN, the poster name and comment text look to be the same size and there are bigger spaces between the posts and paragraphs of each post. Thus, my scientific analysis of the situation shows that MN has 12 lines of text on each page and the Guardian has 17. The MN site is giving me the motion sickness feeling that someone mentioned and a headache.
Of course, the situation is probably quite different on my Nokia Lumia where the font is teensy-tiny, but I need to go and do the school run now (I'm late....ooops).
