I find it very useful. Basically there is great change in the user experience. Thre is web editor with built edition icons instead of markup tags. It is very difficult for the first level user to cope-up with DominoWiki markup tags. But XPages has removed this problem.
But, The editing features must be improved more to the level of a strong WYSIWYG editor. The insertion of pictures and tables is missing. There shall be possibility to directly copy and paste the matter written in MS-word /Lotus Symphony.
One more point : we also need a way to comment on these pages by third person...especially who does not have access to edit the original pages abut would like to be considered by the auther so as to strenthen the contents.
