I almost crapped my pants when I saw this title -- I thought it was a dream of mine come true. For years I've hoped that someone really clever would make every webpage a wiki via a browser extension. Unfortunately, "universal" is here being used to mean "not universal". I'm still waiting. Cmon guys.
I sort of had a similar idea: an extension that would let you point out typos on any page on the internet, and the person responsible for the site (assumed to be admin@whereever, but can be redefined with a link tag on the site) will be automatically informed, or can set a preference using their extension to receive the corrections as an RSS feed that they can feed into, say, their bugtracker.
I too had such an idea. Nursed it for a while, then did some research...there were several failed companies that did this back in the late 1990s. (Didn't call them wikis, and I think the point was to annotate, or vandalize, more than edit.) I'll post some citations if I think of the names...
this is a good idea. but come on, that is one ugly button!
Agreed, way too many colors to hope to be a universal icon.
Universal... except for the parts of the universe that can't be edited.
