When I researched my DEL, I found out that there were two persons with the same name. So, it's very important that when you are doing your researches that you just don't take it for granted that the information is accurate. Due to the fact that we were researching a DEL made it easy for me to spot the information on the person that I was looking for. However, with instances where you might not be aware of the information, it could be difficult deciphering which is the correct information.
I mainly use the educational sites when researching on topics for my classes. Sometimes it means communicating with others to see what platforms they are using and what works best. Going with your gut feeling is not necessarily the best way.
