Following spur's tradition I'll add my summary of 2005, too
My team turned from a being the internet department of an advertising agency to being our own little company.
I got promoted to "Mitglied der Geschäftsleitung" which basically means the I run the store:)
Besides being an overall good year, we gained a couple of large new customers and managed to achieve a 55% growth rate and we have fixed projects for next year which should sum up to least an extra 33% growth
We launched an internet lottery with live broadcating of the drawings every 3 minutes
I looked into switching our web development to Catalyst but had to find out that it's not much different than what we have been doing for 4 years now.
We switched our source control to svn and are very happy with it
We started using RT but found out that its just too big for us
We started using wikimedia for knowledge management
