Which wiki did you see this on? To me, it looks the same as it has been; at least for a while.
Well, as far as I can tell, there hasn't been any change on Wikia's end. Did you install fonts for your computer recently?
Hi, I have not noticed a font change too, is it still the case ?
If you installed Helvetica on your PC, then yes, I guess so.
What do you think?
