Show HN: My new link sharing site

Link: http://this.isby.us/

I've been working on this on and off for a few weeks as part of an apprenticeship program with a Rails shop. I was given the opportunity to create a 'toy' app to learn more about Rails development.

The basic idea is this: If you know people you often share links with, you can create a 'bin' on the site, and share that bin with others. Then, you and your friends can all add and view links that you find interesting. My goal was to make this happen as simply as possible, so there are no user accounts, and there is a bookmarklet for adding links without having to go back to the site.

Any feedback is appreciated, and I'll happily answer any questions as well.

Thanks!
