Ask HN: Does this curation tool exist?

I haven't written the bookmarklet and the site is going through a redesign to use an API but what you just mentioned is my bookmark manager that doesnt require you to be registered or logged in to explore it. It is called Mark my place and it is located at www.markmyplace.com. If you begin to use it I will take into account any changes you want for the redesign. The redesign is supposed to shift everything to the website's front page, and be completely driven by AJAX but if you look at it you can see the potential. It would be nice to have a user to develop for who wasn't just me. Thanks for your time.

Try http://tldr.io/discover - it uses a chrome extension and lets users summarize content (the content also has a nice HN rollover that shows you the summaries of stories). The web page has the summarized links organized by category. You can also use it to summarize your own blog (via an embed). (I have no relation to tldr.io, but I just like the tool).

I built one that runs on WordPress:
