OCD is pretty decent but I'm pretty biased ;) our delegation account has one of the lowest fees it takes and we don't just focus on maximizing ROI but spread it out over many niche communities and when some is left over in the OCD community. You can also track your daily returns here after you delegate to @ocdb: https://thegoodwhales.io/delegators.html and can already start earning on the 2nd payouts after your delegation went through (but then you also stop earning after the next payout when you remove it cause it usually takes 7 days for curation rewards to appear) Not much ways to get involved lately except joining our discord and saying hi, we're a bit busy figuring out the best way to grow from here and what to focus on but we believe assisting more niche communities with our voting power will be great for the chain. Another curation project I can recommend is @curangel.
