I very rarely notice it, but this very article to me is displayed in Bitstream Charter (I think because it contains one character somewhere that isn't present in Georgia) and Bitstream Charter is awfully bad for some reason, probably because I have it in PCF format.

My package manager describes it as A serif typeface designed by Matthew Carter for low resolution devices.

You are probably blessed with not having this font installed on your system, which prevents your browser from choosing it instead of Georgia.

I rarely encounter this problem though, I suppose there aren't many fonts that are only available as bitmap on most systems, and even fewer of them get used by websites.
