Wordnik, which is trying to become the “world’s biggest dictionary,” just opened to the public today.

It includes a ton of user created content from throughout the web. For English Language Learners who are trying to learn the meaning of a word, I’d say it offers too much content and they might feel overwhelmed.  Other dictionaries on The Best Reference Websites For English Language Learners — 2008 would work better, I think.

However, it does offer the opportunity for users to add their own audio pronunciations and definitions, so I am adding it to The Best Places Where Students Can Create Online Learning/Teaching Objects For An “Authentic Audience”.

You can read more about Wordnik in two other places:

Webware has a good post about it today.

The Christian Science Monitor ran a piece a couple of months ago on Wordnik’s founder.
