How do you actually use BoardGameGeek?

I keep seeing BGG recommended as the go-to resource for everything board games, but honestly the site feels a bit overwhelming at first. Curious how people here actually use it:    

• Is it your main source for finding new games or do you rely more on Reddit/YouTube?   
• Do you trust the BGG ratings, or do you find them skewed toward heavy/complex games?
• Anyone actually use the marketplace or trading features?
• For party/social games (murder mystery nights, etc.) — does BGG even cover that well or is it more of a "serious gamer" platform?                                                                              

Trying to figure out if it's worth investing time into building a profile there or if Reddit honestly gives better recommendations for what real people enjoy.
