I rather the dict:// tag automatically correct spelling for me, as opposed to giving a link to a definition...
as in,
[dict://speling] would be replaced with the first word giving from the list of possible words from the dict site (chosen on your homepage?) and returns it, unbeknownst to anyone else.
UPDATE: After having a goodnights sleep, and seeing how many requests there where for new tags... I figured we should make it easy for vroom to implement, so why not just make a
[DWIM://blarg] ala Acme::DWIM ;)
