have you heard of this website??

Guys I was working on my presentation on Pete Buttigieg (sp?) the other day and I was mired deep in my research. I was stuck - I was having an extremely difficult time finding new sources. All of a sudden I found this super helpful website that had a lot of really good information on a lot of different subjects. It was called wikipedia. Have you guys heard of it? Does anyone know if the information there is reliable?
