I just upgraded to WordPress 2.0 and I’m not all that impressed with the results. The WYSIWYG editor (that I was so excited to see included) does not work well. In fact, I couldn’t even get it to apply formatting at all in Firefox 1.5. I would highlight the text, click the bold button, and it would flash bold for a brief period before reverting back to non-bold. No idea why. Also, no way to format pictures (float right, for example) or browse images on the server before inserting them. I switched back to ChenPress, which is much more functional.
Also, the file-uploader is not very useful for uploading pictures. I received safe-mode errors and it would not upload. IImageBrowser worked much better, but I had to disable WYSIWYG editing to access the text area toolbar from which IImageBrowser is launched.
On the positive side, the new admin interface looks great and the usability there has been improved quite a bit. It’s possible to edit plugins, easier to figure out the .htaccess file, has the comment spam plug-in by default, etc.
Eventually, I think the WYSIWYG editor will catch-up with what people need. But at this point, it is an unremarkable first attempt.
