I've been getting to be more and more of an Evernote fan lately, and have started to grok what twitter is really all about (other than twitter spam of course), so I was pretty interested to see how Evernote Twitter integration had been implemented over on the Evernote Blog.
Basically you do a dance following the @myen user on twitter (click link for instructions), and when you're set up you can simply mention @myen in a "tweet" and that note will automatically show up in your evernote inbox. Very cool!
As an aside, you can search for #EvernoteCrazy in the twitter to see what other folks are using it for.
