Here’s an interesting plugin for Firefox if you have Google Wave. To date, I’ve been keeping my browser open on Wave in the hope that someone will send me a message, but that’s quite wasteful on resources. Yes, bandwidth is cheap, it’s not like I’m using commercial satellite or anything like that; but any running process is going to consume resources in some shape or form.
Instead the Google Wave Add-on for FireFox will poll the service for you and let you know if there’s anything new that needs your attention. It’s a tiny widget that sits in your status bar, so it’s not even very intrusive.
Get it here – and if you’re on Wave, I’m firstname.lastname@example.org
