Just started using it myself. Up until about last month I was never really plugged-in to the community and I have found that CloudCred has been usefull to put yourself out there and connect with other people. They have a cool list of tasks that you can knock out for points ... kind of arbitrary but fun. In fact one of the tasks is commenting on this forum!
It's a good way to connect with people and learn a few things in the process. Feel free to join the team:
CXI Team WTF? Talk about VAIN!
Hope this helps!
