XING question application

I just learned a new functionality in XING. When you add the application XING Questions, you can post questions which can be answered by all XING Question users. I always used Twitter for this, but I definitely prefer the structured approach of XING.

To all my XING contacts: Please add the XING Question allplication to your profile, so that I can start asking stupid questions to you also :-)

Another application, you can add to your XING profile is slideshare. Have a look at my profile, to see how it works.
