I once tried a cms called Geneone which could handle forums, blogs, static pages and I think dymanic pages but it placed all content in a single table, which I suspect would cause it to fall over for a busy site. It never had a PM system and I on;y ever saw it on two live sites, one being the author's blog which has since been migrated over to wordpress. It was written back during the php4 era so would need a complete re-write.
You don't have to use just one CMS, say a site needs a blog, a forum, a PM system and a load of static pages it could use for example mediawiki for the static pages, wordpress for the blog and phpbb for the forum, PM system and user management Some CMS software can be "bridged" so that one handles say the login process for the ones that are bridged.
Before you consider any non-free (generally non open-source) cms, you should be able to justify to yourself the costs such as the licence fees, etc taking into account this like estimated site traffic. If you do go for a paid solution, go for one that has a good, clear route to migrate over to a free one should you find that you can justify to yourself the cost of the paid solution once its licence comes up for renewal.
With any plugins for any cms always make sure that as well as keeping up to date with the version of the main cms, always keep up to date with the versions of any plugins and don't leave installed any plugins that your not using.
I consulted for a media company that produced/sold CD's, DVD's, Cassettes, VHS, DAT and a bunch of other media type products. This is going back 6 – 8 years... They were using a Microsoft CMS eCommerce solution and when Microsoft released the next version they dropped support of the existing one and expected that everyone would buy the new license. The issue wasn't that the license was over-the-top expensive; I think it was reasonable. The issue as I recall was that there was no upgrade path. The new version was a completely different system so the upgrade would result in a new installation/configuration and then export/import of products and imagery. The company I was consulting with chose to continue with the unsupported version and I have no idea what they ended up doing in the long run.
That was one of the reasons I decided OSS and community driven software was a good thing to look at :D
Well, only a couple more days and the Poll will be closed. I figured there would be more than 16 people using CMS frameworks but I suppose you learn something new every day ;)
I'll try this again next year and see if I can get some more input.
Cheers and thanks for the input.
I prefer Joomla..
I used Joomla and it is great, but I find WP easier to deal with and I noticed the costs for maintenance are lower now that I'm using Wordpress (i think the reason is that I can do more things myself, and not refer to any developer)
