I think if you are just skulking SDN there is a lot of high-yield information when you first discover the site. Common tidbits of wisdom like apply early, broadly, have a highly targeted list of schools, interview tropes/etiquette, value of ECs, stay committed to an EC for a long time, have some strong clinical experience...etc. Basically, how not to have any red-flags on your application and maximize your ability to get in. This was invaluable to me as a pre-med and I'm glad I discovered it because I am now much better equipped for my eventual cycle than I was before. At times, yes, it has made me a bit neurotic but I try to keep myself sane.
After a certain point, however, the value of the information becomes low-yield and you can only derive value from SDN by discussing, which is why I made an account. I feel even though I'm by no means an expert on a lot of things (most things, really) I have a particular set of skills, life experience, and knowledge that I can use to help others. I enjoy having a good debate on SDN with other pre-meds about admissions, medicine, and policy. I learn a lot that way. Even in the tireless URM arguments that frustrate me to no end. I have the utmost respect for everyone I debate/talk to on this forum and thoroughly hope everyone succeeds. I've learned a lot even from the people who I disagree with the most strongly - barring anti-vaxxers and trolls of course.
SDN taught me about DO! I never heard anyone even talk about DOs in high school. My new physician in my college city is a relatively young DO (excellent doc, by the way) and when I told her I was a pre-med I didn't have to sound completely ignorant when I asked her about her journey to medicine, how to pick schools, and that seemed to make her happy. I have SDN to thank for that. That's why I gave them my money and donated.
An adcom that just scanned the front page might laugh at the incredible number of applicants willing to eat a poop hot dog but I think any regular member would see that SDN is a great thing.
But also...remember remember the rescindment of November.
