Basically instead of saving bookmarks you are saving parts or a section of a page, here more:
” If I am doing research for a client, I can highlight the portion of a web page that I think would be useful, click the “Snip” button on the toolbar, and that content, along with the URL, is stored in my eSnips account. If I want to save a screen shot, I pull down the “Snip” menu and select Screen Shot. I can even specify whether I want to grab the full page or just a section, and - if the latter - whether I want to snag a portion of the page in the shape of a square, rectangle, ellipse, and so on. I can add a title and description to the snipped content, and then I specify in which folder within my eSnips account the file should be saved. “
The features of this tool focus on snips of pages so it is geared to do this one function well, but it is also possible to do it with a tool like Furl (clippings field is for highlighted content from the bookmark, and comments field is for your thoughts).
Another related tool is Purple Slurple, which enables you to alter the URL of a page so it points to the exact spot you imply.
ADDED 20/09/05: What I forgot to add is that you can actually store files from your PC on e-snips (this is geat when you haven’t got your PC handy, or as an alternative to saving it in an email), and invite people to have a look (although your file eg. a word document, doesn’t have its own URL), hopefully Furl will implement this in the future…actually you can upload files from your PC to Writely, and share them with people, or share them with everyone, and your file has it’s own URL, so it’s your own webspace to publish your word documents…
