So you wanna see who’s online?
Who’s Online is not perfect, but it works well enough in determining who was online and when.
You won’t be able to get a real-time list of people that are currently online, but you can see who has been active in the past few minutes. The application will fade out your friends the longer they have been away from Facebook.
The profile box is slow to update (but it does update). Clicking on ‘See All’ will update your list.
One minor complaint I have is the application will spam your mini-feed every time it updates your list. But that’s easy to fix in Facebook’s edit apps page.
I currently have it installed and am still debating it’s usefulness. It’s worth installing and checking out for yourself.
