A while ago I made a bookmark add-on which could be used to do something similar. But it sunk without a trace on HN. Posting it here as readers probably already interested in bookmark related stuff...
I submitted a "Show HN" post recently and watched it sink down the "new" page without any interaction.
I wonder if it's because I created a new account to post it, or more likely I had a terrible/generic sounding post title.
It's also difficult to pick the right time of day to post. I thought I had it right - picking Monday morning west coast (US) time, but I guess there is a big difference between just before and just after people get to work!
I would have liked to hear what people think, even if it's "This is bad, and you should feel bad".
