i love zOmg i still play a lot of the time. I remember when it first came out and you had to be a beta player to play it. Its come a long way since then and it does get boring if your alone but i play with friends all the time! So yes some people still play zOmg.
Yes, some people still play. However, it is not as much as it was back in 2008 or 2009. A lot of things happened and one of it was the newly (actually it's 1 and a half years old now) released Deadman's Shadow which increased the player traffic a little. zOMG has lack of updates since 2010 and most bugs were not fixed yet therefore putting zOMG in maintenance mode.
