TUAW disclosed an affection for Evernote a little while ago, and our love of Skitch is no secret. While love triangles are often a logistical nightmare, this one actually works out in a fairly organized fashion. An entry at the Evernote blog details the use of Skitch to input notes into Evernote, complete with annotations. It's simple, if not a bit obvious in a why-didn't-I-think-of-that way.
There have been several other thoughts on extending and integrating Evernote, but one of my favorites was a bright idea for setting up a liaison with Jott to facilitate voice transcription of on-the-go notes.
