You may have noticed that there's a new logo on the site today. This is the new official logo for the site.
It's natural for sites & businesses and so on to have their logos updated to "keep up with the times" as they say.
For a cool bit of tech history, checkout some past logos for Apple
, and then there's Google's "Doodles" (and here's their archive of Holiday logos for the past 10 years
) which they create for all sorts of special occassions.
So, no reason to be alarmed when you don't see the old logo on your screen.
