Thanks for the replies.
First, the reason I posted this is I enjoy technology, among other things. I'm not interested in just having expertise in computer hardware, operating systems, etc. Website creation/development offers me a bit more creativity. This may sound crazy, but I feel that with all the virtualization of servers, there may be fewer opportunities in the computer hardware and network support areas in the future. I want to keep a job!
Also, as I have indicated before, I work part time for a Midwestern municipality, and our deputy clerk, who also has some IT knowledge is mildly interested in CMS software. One of my tasks is to maintain, and further develop the website for the city. Our web authoring software is a bit out of date and while the city is on the small side, there are quite a few web pages that go into making the site.
I'm trying to look to my future, professionally speaking, and I just wanted some idea of experiences with a CMS.
Note to Mike Griffin: Yes, I do know that there are some self contained CMS's, Plone is self contained I believe, and yes I am researching that one.
