I'm a Junior sysadmin at a company with less than 300 people, on a team of five.

We all do a little bit of everything, and we have our specializations as well. Password resets, walk ups, network outages, development servers down/cranky, spilled coffee on your laptop, provisioning new users or new servers, we basically do it all. Everything except emergencies in production, our manager and our senior sysadmin handle that.

I specialize in Linux and VMWare stuff, the two other Junior sysadmins specialize in Windows and network administration respectively, so we can still be generalists while also having someone we can consult with if we're feeling fish-out-of-water with a specific technology.

It's my first job out of college. I used to work at my university's help desk and also interned at a couple of much larger places. When I started I was pretty surprised at the lack of division even though they gave me the general picture of how things worked there when I was interviewing. But as I've gotten more familiar with the place, I got comfortable with it. It's actually pretty exciting. I get to touch a lot of different systems, the user only ever has to deal with one person, and its nice being able to take an entire problem from tier-1 troubleshooting all the way through sysadmin-level resolution instead of having to hand off the ticket just when something is getting good, or worrying that you got it wrong and the sysadmins are just going to yell at you.

So, in short I suppose, it can actually be kind of satisfying when those lines are blurry and I don't think there's any real reason to have them clear unless your organization is huge (like maybe 1,000+). But also, you know, I'm fresh out of college so maybe there is and I just don't see it yet...
