Up-to-date lineup of WYSIWYG editors?
The reason you see so many abandoned projects is that instead of maintaining multiple separate modules for individual packages, work has gone into making those packages compatible with the WYSIWYG API module. By abstracting the editor library from the editing interface, you gain the ability to use different editors for different input formats, and it becomes quite simple to swap one out for another.

According to the project page, WYSIWYG API has direct integration with


CKEditor
FCKeditor
jWysiwyg
markItUp
NicEdit
openWYSIWYG
TinyMCE
Whizzywig
WYMeditor
YUI editor


as well as a whole host of useful plugins.
