Topic: What do you do for work?
Just post what you do -- try to be more descriptive than a job title; "systems analyst" sounds fancy and all, but doesn't really tell people WHAT you do as a systems analyst. Sure, some job titles are relatively self-explanatory, but feel free to expound upon them! If you don't feel comfortable saying where you work, you don't have to; you can say what sort of company it is if you'd like, but that's not necessary either. I'll start.
I work as a web systems administrator for a large toy company. My job is basically to keep the public-facing web site online, deploy new code to the servers, fiddle with the server configurations (mostly redirects) as our various business units see fit, and so on.
