Black text, white background, anything else is absurd.
Ditch the boxes round the comments they are seriously ugly and not helpful.
When I ask for the desktop version, I want the desktop version FFS, my phones screen has the same resolution as some laptop screens.
Get rid of the option to choose all insightful, all interesting etc comments - it's pointless because of the crossover between these things and it would lead to some bizarre meaningless threads being displayed. Not useful.
Bring back the user info, friend foe, userid etc, slashdot looks raped without it.
Things worth keeping:
The ability to mod without scrolling to the bottom of the page and hitting the mod button (I open the post in a new page to mod it so as not to lose my place/it's quicker)
The ability to collapse threads.
But that's it, the rest is a seriously bad downgrade.
Things that should have been improved, why weren't they?
The text box I'm typing in right now is tiny - why?
There is 'allowed html' It would be nice to have some buttons to put those tags around some text when you highlight it.
To any damn fool who's answer is well 'why don't you go and re-write the code yourself', I have the question - why didn't you build your own house and car?
