Uptime displays users... does this count people viewing the website?

I'm running a web server from home and haven't given out the domain name at all. I haven't ever planned on much traffic either so I haven't done much to secure the server. If something happens to it at this point, I wouldn't care. I've only made 3 pages and there isn't anything confidential.

When I run uptime this is the readout:

Code:

---

11:03:51 up 4 days, 20:02,  2 users,  load average: 0.08, 0.02, 0.01

---

I'm the only user logged in. I logged in via SSH and haven't used sudo or su. The first thing I did upon logging in is run uptime.

Is there any other reason besides someone else connecting remotely that it would show that there are 2 users? My only other guess would be that there is a bot indexing the website or someone viewing it.

utpime only shows system users. Run the command "w" or "who" to see who is logged into the machine.
