I believe Visual Studio Achievement extension is a very nice plugin to have it on Visual Studio. It is running in the background while you are doing your daily tasks to analyzes your actions and according to the progress you are going to get an achievement badge(s).
Most often developer hard work and efforts will not be noticeable, till he/she achieved a huge thing in short time or discover a hidden bug within a very short period. But having VS achievement in place, this is will not the case again. The tool will analyze actions on Visual Studio and unlocked the deserved achievement to the developer according to actions. These unlocked achievements will be posted to Channel 9 profile for the developer (thus having profile on Channel 9 is a prerequisite ).
Once you have an achievement granted, a popup will appear on the right-bottom corner of your screen with your achievement badge and you can check your achievement on your channel 9 profile at any time.
This extension is live now and you can install it from extension manager at your Visual Studio 2010. after installing it, you will be asked to restart your Visual Studio, after the first run, you will be asked to login with your Channel 9 profile.
I believe this extension represent a new way for developers to highlight their skills in a common way. The same rules applied on everybody…
It should not be the judge on developer experience but I think it is very good extension that will create a very good atmosphere between developers for a fair competition
