I think this is actually a pretty cool idea, but for it to be successful - 1) The app is a little rough around the edges... needs at the least a method for "flood protection." 2) Ability to adjust opacity, as it does take up a decent bit of real-estate. 3) MOST IMPORTANTLY - this is a great little bookmarklet app for community-driven websites like HN, reddit, etc... but the owners/admins of these sites need to PROMOTE the use of it. NOTE: This could also be popular on other types of sites as well.

For example, when this was on the front-page and i tested it out there were a little over 30 users on chatting, today its moved down to item 64 in the list and no one is using it. So it would definitely need to be promoted by the site for it to become popular.

I just had another thought, the developer of this bookmarklet could do a website that provides a list of web sites with the ability for user submissions and provide a sort of jump list. Hopefully there should be a way for the app to report the # of active users for each site in this scenario.

Anyways, I like it.
