if you are quite active on the forums, it is quite annoying to change your font or colours every time!
I am quite active on the forums and while it's not annoying having to format my messages, it is annoying to read a text in a bright colour on a dark background, especially late at night. There is a reason why white isn't the default text colour - to reduce eye strain. There is a reason why when there's a lot of text, it is recommended to use sans-serif fonts. There is a reason, why fancy handwritten fonts aren't used in text. It's not just "more ways to express myself"
all the text in the forums are readable
Just because something is readable doesn't it's easy to read. Readability drops without proper spacing and legibility drops with weird fonts. Google russian cursive for example, or...
Here I'll show you something else, let's take a warm color family with a standard font with unnecessarily bigger font size:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. This is a sample text written in various colours. Ut laoreet, tellus vitae tempor tincidunt, sem est condimentum risus, in facilisis nisl lacus eget mauris. Maecenas leo elit, suscipit eu mi vitae, sodales aliquet ante. Here I'd like to show emphasis by changing the colour. Maecenas imperdiet tincidunt velit, quis tristique neque pretium id. Here I'm once again putting emphasis on the text until the end of the paragraph. Aenean sapien urna, feugiat dictum ultricies vitae, vehicula quis tellus. Curabitur quis nunc id massa ullamcorper porta. Etiam fringilla orci dui, sed ornare lectus molestie quis. Etiam luctus ante enim, eu aliquam tellus bibendum id.
Seems normal, doesn't it ? But here is the same text with Protanopia - Color blindness to red
Edit:
many people already change their text consistently
I am aware of this, here's Head Staff using a different font color:
Here's staff using golden colour for their text, however, the link uses a very similar colour, making it hidden in the text.
Dark green on a dark background:

Another one:
These were mostly about low contrast and low color difference, what about too high of a contrast with colours that burn your eyes at night... ?
Here's a discussion regarding white text on dark background:

And a blog that's linked there:

And here are some quotes from both of them:
However, most studies have shown that dark characters on a light background are superior to light characters on a dark background (when the refresh rate is fairly high). For example, Bauer and Cavonius (1980) found that participants were 26% more accurate in reading text when they read it with dark characters on a light background.
People with astigmatism (aproximately 50% of the population) find it harder to read white text on black than black text on white. Part of this has to do with light levels: with a bright display (white background) the iris closes a bit more, decreasing the effect of the "deformed" lens; with a dark display (black background) the iris opens to receive more light and the deformation of the lens creates a much fuzzier focus at the eye.
And here are the results for default text colour and default background:
Looking back at all the images I provided, It's funny seeing most of them are from staff, especially after they stand by their "professionalism" so much in other posts.
