SDN is truly addictive.
When I had joined this community the intention was to resolve my day to day issues which occurs in my routine work,
this community especially developed to the help of SAP users.
Everyone thinks that they have just sign up put a query In specified category,
there will be some knowledge exchanges (in terms of reply) between people, select best amongst them and things done.
As and when you work with this community you can feel homely to play with it slowly you can get adjust with it and reply to another one whatever the post is there(little R&D stuff). (then you tottaly forget about other social networking websites and stuffs)
The biggest benefit is to gain hell lot of knowledge from it, secondly most strong networking with people of your domain finally the day will come the second most page you open in the browser must be SDN.
