There is some inconsistency in the wording that kind of bugs me. In the following...
- Servers
- hardware
- Operating Systems, including linux windows-server-2008 freebsd solaris
- Server Software, such as apache2 exchange-2010 sharepoint
- Virtualization, including vmware-esxi hyper-v kvm
... we go from using "including" to "such as" and back to "including". The meanings of the words/phrase in this case are essentially the same, so we should settle on one or the other. I propose cutting out "such as" and changing it to "including" and using that for all future instances where warranted (I'm thinking specifically of John G's proposed edit).
