I'm currently in the process of switching my Werkstatt site from TWiki to Drupal. TWiki is a really cool and powerful Wiki plattform, but for a mostly one men administered site with different use scenarios including blog entries, static pages, image galleries, forums, it is not the best solution. Another not so perfect aspect of TWiki is its text files based storage backend. Although, I love the easyness of just having text files (you can easily search and change from commandline and migration of your data is also easy done) it comes at a high cost, the whole page was really really slow, even if only serving one client. Drupal uses a database as storage backend with is a lot faster when using dynamic content, tags, complex security schemas, etc.

So, after migration my old blog posts (formerly called news) I will look for a wiki like replacement of Drupals standard content editor. I don't like having links and markup annotated in HTML style.
