I thought I had a post here about which libraries I have and what I use them for, but I can’t seem to find it. Would writing that up be helpful? I don’t think I do anything very complex.
I have one library that I use to capture interesting articles and key paragraphs, tweets, notes that aren’t for publication, etc. This is more to have a local, searchable copy (since so many things disappear or change) than to do the writing and linking.
That’s all done in MarsEdit where I keep a large number of drafts for posts and updates, with “tags” in the title to help find them. I have a bunch of scripts to help. MarsEdit is not really designed for this, and I don’t think I have a particularly great system, but I like it better than my old way of using separate apps for collecting/organizing and writing. I try to capture (using the bookmarklet) everything that I want to link to directly into the appropriate draft.
The other place where EagleFiler helps is in finding old posts that I want to reference. Google is not always great for this, and MarsEdit has limited browsing/searching, so I have an EagleFiler library that stores my published posts, so I can browse by tag and do more powerful searching.
