Tools for developers are really good. IDEs and DVCS are pleasure to work with. But try to work on a spec, RfP, Offer, etc. with Word and Outlook. Online wikis are quite good but it is not possible to send them via email to a third party.
My idea for a text editor: * storage: wiki text files + embedded git repo * save all to a single file, but with possibility to access and edit the contents via web server / web app * possibility to squash all edits and send a clean copy (branch) as an attachment * possibility to incorporate changes sent back, thanks to DVCS * two edit modes: WYSIWYG and markdown style for experts * two client modes: standalone with thick client (based on Webkit) and html5 client * possibility to access and modify the contents via APIs (Java, Ruby, ...) * optimized for screens, not for A4 / US letter pages
You get the idea. Corporations would love something like this.
