I covered myths #1 and #2 so it's time to start getting into the things I learned while working in Sammamish. Learning #1 is that I never saw so many people depend on IM. Everyone was running Microsoft Office Communicator and they used it.
It's was a great way to ask for help from a co-worker on a case when you are on the phone with the customer. It was also used as a primary means of communicaiton with the support folks in different parts of the country or world.
In the product groups there's a mix. There are people you can find on IM and then there are people who just aren't on the corperate IM train.
On a related note... I only have one freind left using AIM. Everyone else I know now is on Messenger. I remember feeling guilty when I started at Microsfot for running it, but it was what all my freinds from college where on. Now I only have one freind left to switch before I can delete the bloated adware AIM client off of my machine for good.
