I have an idea for a plugin that would create links to websites like Amazon, Wikipedia, Dictionary etc.
It could use the wiki tag system for generating the links
[Website[Link]Title]
Instead of creating a link with Steve Martin. I could just do [Wikipedia[Steve Martin]] and it would generate me the link Steve Martin.
Amazon links could just use the ASIN [Amazon[0783115202 ]The Three Amigos] would generate The Three Amigos
Dictionary usage would have the same system: [Dictionary[plethora]]
Those were just some examples, it could handle more links to things such as the Wordpress Codex, Google, TV Tome etc.
As a name suggestion: Plethora.
