It's that time again! The good news is that the company is still intact and working on projects (DOOM 4 for sure).
The bad news is that id laid-off a batch of people earlier in January, probably because they didn't need 100 people to sit on a brand-new team.
Also, it's unfortunate that this birthday hasn't been recognized anywhere, not even on id's own blog. They're probably too busy dealing with the massive success of Skyrim. Grats!
