Well, first let me stress that I never encountered any serious problems with my Plone site. Yet, over the last couple of years Plone has become more and more complex with a rapid succession of new technologis, complex xml-based configurations and layers upon layers of abstraction. All this added up to an application stack which is very difficult to understand and maintain. Starting with Plone 3 upgrades have become frustating and error prone. The constant introduction of new technologies are only manageable with continuous learning and with continuous development work. Time which I do not want to invest.
Early this year I finally had a site which was running flawlessly yet which I could not update due to my limited knowledge. At the same time I could not reinstall the site in the current configuration as certain packages where not available any more. This gave me a system which I neither could restore in case of a server crash nor which I could maintain for the future in one way or the other. Therefore, it was time to move on.
