Working With The Community
The community perspective
• Earn respect by saying what you‟ve done and how you‟ve tried to find
an answer
– Where did you search?
– What did you try on the board?
• You aren‟t entitled to an answer
– Show that you are willing to work for it and the community will feel you are
a part of it
– Impatience implies that your time is more valuable than others in the
community
