I have a linkblog working in WordLand now, but it's not yet ready for use outside of my testbed.
There's a bookmarklet. When you see something you want to add to your linkblog, click the bookmarklet icon in the browser chrome.
WordLand comes the front, confirms you want to add a linkblog item, then displays the edit box with the text pre-filled with the title of the page you came from. (Exception, if you had text selected on the page you're coming from, that text is in the edit box and the title is in the title field in WordLand.
Invisibly it has remembered the page that you were coming from, you can see it by choosing the Edit Linkblog Link item in the context menu. (It will probably become more visible in a subsequent update.)
After editing, when you're ready to publish, you can click the paper airplane icon. The item is posted to your WordPress blog, and also to its RSS feed.
We also maintain a special feed that might be more suited to reading linkblog flows. I'm building new software that takes advantage of some of the features, it's up to WordPress developers if they want to adopt these features, when they're stable (they are most definitely not stable now).
Still more work to do before these features ready to ship, but will (hopefully) soon.
