The point I was making was that I won't spend my time or money on new technologies just for the sake of it, I need to see a real benefit first. If I do see a real benefit then I'll embrace it and tackle it with both hands.
The second time (Not the last time) I rebuilt the web site was in 2004 and this was done to get rid of the tables for layout and reduce and tighten up the code. This was done as I knew I'd see a benefit in page load times and SEO/Traffic.
Fair enough, if you've checked out your competition and new commercially available systems and don't feel they offer anything extra that could increase traffic to your website, or improve usability that's fine and dandy.
It isn't always commercially viable though to build your own system from the ground upwards. I haven't got time to build my own CMS any more, new systems are far too complex and feature packed to make developing my own system commercially viable. I make my money building and designing websites, not software, and I can provide better value for my clients if I download and install a free plugin to add social networking feeds, for example (bad example, they're relatively easy to create but you get the gist), on their website rather than developing one from scratch.
I don't know what area of business you're in, but if it's not software development you might find your time is more effectively spent installing a commercial system and spending the time you've saved on networking and promoting your products instead.
No-one really knows what new developments around the next corner, so being able to download and install the latest version of your shopping cart software with all the new essential whistles and bells website visitors come to expect, and get it up and running in a few minutes makes good commercial sense.
Ignore the above if your requirements are not covered by commercial systems and a bespoke build is the only option.
