You might want to look at Canaware NetNotes
if you're willing to rethink a little of your workflow.
It's more along the lines of one of those tree-notes type PIMS. Left pane is a hierarchical tree (folders & docs). Right pane is the actual document.
I don't know how much post editing you do. But if you primarily allow the clips to stand as is, then this might be something that would work for you. You don't get tags, but you do have a customizable tree. And you can also have multiple libraries - which can be merged if necessary. Plus, there's a very good built-in search function. The URL is automatically saved for anything you store in NetNotes. (The navigate button will take you directly from the saved page to the webpage in your browser.) Document title is derived from the webpage itself. But you can freely edit and modify it if you like. There's also an edit mode for the clip itself. So you can freely add notes or whatever to the clip. You could even create a doc in it's entirety if you so desired. The latest version has added a few additional features including the ability to edit tables and images in a document.
Going with Canaware would save you the intermediate step of going through CintaNotes because the clips become part of your library the minute they're saved. I initially drop all my clips into a SORT folder. When I have the time, I eventually move these clips (with optional annotations) to their final resting place in my doc tree. Works really well.
I use CintaNotes too. But that's more for quick & dirty grabs of stuff like software I'm interested in looking at. In the past I used to create temporary bookmarks in a "Look at" folder under Firefox. But that got way too cumbersome.
My workflow is pretty straightforward - and constantly evolving.
Right now the main point of entry into my infoworld is an RSS reader (Sage) which I use to stay on top of websites and topics that most interest me.
Anything that catches my eye for serious later reading gets sent to my account at ReadItLater
via a FF plug-in or an app on my smartphone. I bought the Digest option from RIL when they offered it at discount (perpetual one-time only license fee) to people participating in their beta. It was only something like $15, so even if they eventually pull an about-face ripoff like so many other "lifetime" offers have, it's not big money we're talking about. (Sorry to sound so cynical - but I am cynical
anytime the word "lifetime" gets used in the same sentence as "license.")
Anyway, if it's something that I think worth archiving, it gets sent one of my Canaware NetNotes library folders, depending on the topic.
If it's some info I want to keep - but less permanently
- (like the current selections in either my "favorite" or "genuinely interesting" software lists) I'll put that in CintaNotes along with a tag or two.
Don't know if any of this helps, but there ya have it.
That's my story - and I'm sticking to it!
