What are your reasons for joining online forums?

There are too many reasons, but the one that stands out, at least for me, is exchanging experiences. Suppose you’re looking for the best online yoga classes. You will find tons of them just by googling. They may all be highly rated, but an online forum allows you to explore more.
You can ask other people about their experiences without testing each online class one by one yourself. Of course, the support and motivation on online forums are great reasons.
