I am not a huge fan of linguistics, so I don't particularly love words for all the history and usage they come loaded with. But I do adore words because they make the page I am reading taste better. Here are a couple of my favorite word links:
1. freerice: rice for people who need them and words for people who have rice. What a marvelous concept! Great for the GRE studying too.
2. wordnik: so effortlessly puts all the info about a word on one page, including definitions, examples of usage (including usage in twitter posts), pronunciation, and flickr photos I suppose tagged with the word.
Will be back with the ramblings-on-what-I-am-reading posts soon!
