I don't know if I share this experience with other members of the Academia.SE community, but for me text shade is way too light. For me, it makes it harder to read (and focus on content) plus, after not long time (~10min?) slightly painful (~dry eyes).
I know it has some positive consequences too (i.e. not spending too much time on Academia.SE), but I am not sure if it is desired effect overall.
Why I am writing it now? In general I prefer dark text (like
#000000) to gray one. During the design phase I didn't want to be too biased (especially as I do like the design). I though that I would get used to it. But I didn't (it's not getting any better).
I know it may look nice. But I am here not for looking, but for reading.
Are you experiencing a similar problem?
(If it is only my, I will do some CSS hacking on my side, but if a non-trivial fraction of users share my pain, then it might be worth talking about tweaking it globally.)
