First, it's winter only up there in the northern hemisphere. Honestly, I live in Brazil and although the first time I saw the new logo I imagined it had something to do with Christmas, it just looked weird (and the last 'o' is cut out a little).
Fixing the last 'o' would be good because it looks amateurish, as for the logo, it's just a matter of taste and doesn't affect the site's image.
