Have been looking at different programs and have found that Joomla seems to be one of the more popular choices for webpage design.

What do you folks think? Is it quality? Is it difficult to install? What about longevity? Anything better and easier?

I've never used it myself, but it looks like a reasonable content management system from what I just read.

I've used a number of wiki systems. They all do pretty much the same thing.

Pick one with the features you need and with quirks you can live with, and go for it!
