Ok, this post has been shamelessly ripped from Aalaap’s blog. So I guess I owe him one!
You probably don’t have Google Buzz in your Gmail yet. So here’s how you can use it on your PC without having to beg for invites.
Fire up Firefox.
Install the “User Agent Switcher” add-on and restart Firefox.
Go to Tools > Default User Agent > iPhone 3.0.
Visit http://google.com/buzz and start buzzing!
Firefox will ask you if you want to share your location with the website. Say yes!
When you’re done buzzing, switch back the user agent to default.
How does this work? It’s so simple, I feel shitty writing this. Google Buzz isn’t available in Gmail for everyone yet, but mobile web access to it is open. At least for those using the iPhone. You can login, post updates, follow people, comment on others’ updates, get updates from nearby and all of that. So you get Firefox, make it pretend that it’s an iPhone using the UA Switcher add-on, and use the mobile version of Buzz through it. Voila. An added advantage is that Firefox also supports geo-location – the same HTML5 API that’s used on the iPhone – so you actually get location-aware information.
