Yeah, there's a difference between a regular HTML page versus dynamic web programming, which requires knowing a scripting language like ASP.net, Java, or PHP, as well as database programming knowledge (any major site that revolves around constantly updated content, whether by users or administrators, involves dynamic programming and a database -- this forum site, for example, is using a dynamic script).
I shifted careers about 7 years ago -- I was a librarian for a very short time period before deciding it really wasn't for me (wish I'd figured it out sooner -- all that money for a Master's down the drain!), and went back to college to become a programmer. So I get to make sites like this every day for a living :)
I enjoy programming as a hobby, too, and to give back to the communities that I'm involved in; I've never done anything for the intention of making money, it's just something I do for fun. Sometimes a site takes off and does quite well (see my profile for one of my bigger sites, if you're curious), and then other sites just don't go anywhere. A lot of it has to do with getting the word out so you can build traffic, and good search engine placement. Advertising is another aspect, as well.
I've decided to go ahead and do this. I've registered the domain, and will begin building the site. I'll post back in this thread in a few weeks once I'm ready for testing and feedback. Thanks everyone!
