On Tuesday (today, for many of you), the wiki service Wetpaint is announcing a series of new features - they're already live on the site.
The non-widget stuff includes custom URL domain mapping to your personal or business website and autolinking (it scans content pages and suggests links to other pages within your wiki). You can also upload attachments like Microsoft Word and Excel files.
But the most interesting new feature to me is Wetpaint Widgets. This feature means you can now add YouTube and Google Video players, Vizu polls, Google Calendars, Photobucket slideshows, Meebo IM widgets, Gabbly chat and RSS feeds to your wiki. Additionally, you can add any widget that uses the "embed" or "iframe" tags. After testing this, we're left wondering why every wiki doesn't support widgets.
If you need some cool stuff to pimp your wiki, check out the MySpace Codes category.
