I would really like to replace Evernote with a self-hosted solution. Wallabag is one alternative that’s pretty attractive. It’s open source, supports imports and exports, and nice on the eyes.
What’s currently holding me back is the lack of an Evernote importer (I kind of expect that, and am eagerly looking forward to writing an XSLT to make that importable ;-) and the lack of features in the browser extension. Basically, Evernote’s web clipper kicks ass, so I’d really like to keep the selection tools.
