“Shelfster is a free tool that attempts to bridge the gap between note taking/web clipping and annotation/social sharing. This is a good thing, because Evernote, as awesome as it is, just doesn’t share as well as it could. For example, if you want to share a single note in Evernote, the only way to do it is by email (or by email to a service like Ping.FM, but that’s a different post altogether). You can’t find information via Evernote, either, socially or otherwise — Evernote is mainly meant for note taking, and it does what it’s meant for extremely well. With Shelfster, both sharing and searching for information is pretty easy.”
