I work with a lot of different clients and team members at HiDef (www.hidefweb.com). When scheduling meetings via email thread started compelling me to pull hairs, I started searching Google for "online meeting scheduler" and happened upon several solutions, one of which was Tungle.

I invested more heavily in trying out Tungle because it connected seamlessly with my Google Apps account. I signed up with Tungle, connected my Google Apps Calendar, and then boom, I was done and could show my availability to anyone who wanted to set up a meeting. No longer would they need to broadcast a message to four people saying, "How does 1pm next Wednesday sound?" Rather, they'd be able to check my calendar and have my answer in a glance.

Of course, scenarios like this will be wonderful once everyone adopts a socialized availability scenario, but I've found Tungle to be a value proposition nonetheless while the world slowly moves away from email to schedule multi-party meetings.

How could Tungle improve? Finessing the UI would be helpful, as well as communicating more clearly what's happening with the user interface. I think general usability will be steadily improving.

I've told several buddies of mine about Tungle and found them receptive of the new tool, though unless they are early adopters like me I'm finding that folks have a hard time moving away from their Outlook or iCal addictions easily.

Tungle is ahead of the curve when it comes to meeting the needs of the likes of me: a web developer who needs to share his schedule not only with team members but with clients of long-term projects. Give it a shot!
