I always believed that technology can help immensely in learning and that is the reason I try to use technology in best possible way I can. Since 2001, I am using YahooGroups for astrology learning and discussion. The day Facebook groups came, I am also using Facebook group for astrology learning, information sharing and discussion. I always loved Google products and happy to see announcement of Google Plus Communities yesterday. One good feature about Google Plus Communities is categorization. We can have one single group and have a separate section for each topic like Traditional Astrology, KP Astrology, Lal Kitab, Jaimini Astrology, Tajik, Nadi, Western etc.
Here is the URL of my Astrology Community on Google Plus - https://plus.google.com/communities/114472931820343160921. If you are the one who loves astrology discussion on Internet, this is a must join community for you.
