Ok, obvious question: Are you in a populated area? Some servers are less populated than others, so some areas may seem 'dead'. If you're in the tutorial, there are some servers I have never run across a second person while there. Galaxy City as a starting point is also usually fairly quiet. On villains, you will usually see a few people in Mercy, but again, sometimes the tutorial is empty most of the time on some servers)
Also, the time of day you log in will effect player load on less populated servers. I play mostly on Victory, and the heavy load there is in the evening between 6pm and 12pm est. Some servers have a higher count of players in other countries and may have a sustained load at odd times. (Note that I cannot comment on European servers, as I have never played on them)
Sometimes you will be out of sync with the server and you will not see baddies, other players or NPCs. If you think this may be the problem, hit /sync in your chat window and it will attempt to resync you to the server.
If you're unsure the game is working properly, you can always make a toon on Freedom (assuming you're on the US servers) and load into Atlas Park. if you don't see anyone there, then something is wrong. (but I doubt it is)
It's also the busiest travel day of the year in the U.S., I imagine many people who would normally be playing are traveling for the holiday.
Also, if you're used to other MMOs where everyone's outside killing 10 fruitbats, collectiong 25 pieces of chewed bubblegum, running errands (usually by actually running,) you won't see that here. There are a (very) few outdoor hunt/patrol missions, but for the most part, any team with a mission is in an instance.
