Same experience for me with HN Thread http://kaspa.rs/hn-bookmarklet/. This seems to work much better.

Let's take this url as an example http://daneden.me/animate/.

With HN Thread I get one page.

With Hacker Panel I just get the submission screen.

With this bookmarklet I get all three times the page was submitted to Hacker News.

Thanks OP.

Sorry, it was using the old API which is now taken down. I've updated it to use the new HNSearch API, so it should work well now. You can get the updated version at http://chetan51.github.com/panels/hacker/.
