Starcraft confusion

I used to play SC when I was a kid. I decided to install it recently and play but there is NOBODY online. Am I doing something wrong

Playing at the wrong times… Probally… Usually there are allways people online.
Other than East USA Server, and Europe at Night.

Korea, West USA usually allways have people.
You also can ladder, most times you will get people at some times faster than other times. Depending also on your MMr.
Not sure about the asian server.

Please tell me, is this the same Starcraft we played 20 years ago?
