As there are many doctors social networks there are also patients social networks , most of them are created for the same aim to connect people with similar conditions , but some of them are created for different goal , category and clients . Patient 1.0 was the web user who is looking for simple reliable information for his condition , symptoms , medication and complication , but Patient 2.0 now has more features than before to connect with specialists , ask them as well as connect and share with other patients and learn from their experience .
