Google Spreadsheets invites using chat feature
I signed up for an invitation to the new Google Spreadsheets beta, and it only took about a day for the invite to arrive. I played around with it, saw some cool features, but wanted to show my friend what it was like. I couldn’t see any “Invite” button or functionality in the application, but I did see a “Share this Spreadsheet” link at the top-right.
Clicking the link opens an invitation sidebar that allows you to invite others to read or edit the document:
You can only invite users who have Google Accounts, but hey: who doesn’t have one by now? As soon as the invited user opens the spreadsheet, the sharing section changes:
Clicking “Chat with …” displays a sidebar allowing the spreadsheet’s users to chat while editing the spreadsheet, all in real-time.
Keep up the suprises, Google 
TechCrunch
I recently stumbled across TechCrunch, suprisingly enough, Digg.com had nothing to do with it. It’s an awesome Web 2.0 blog / commentary, but it’s not like your average “Hey lookie! It’s BETA!” junkfood. They actually do a great job of evaluating and providing insight into some of the more interesting services and products out there. Happy browsing!
Pandora – Social Music Genome
http://www.pandora.com/ - wow.
Like Last.fm, it’s a social music service, but it seems so fluid and intuitive that your initial response might be like mine – “Hmmm. Why didn’t I hear about this before?” – the reason: the Distributed Human Technology Mind Link (DHTML) is ever-changing and dynamic. Welcome, Web 2.x; welcome.
