I live on 2. I simply stink at writing but my big fat mouth can always get be some good rewards from comments. I would need to devote a lot of time if I were to do 3. Just being on steemit is busy enough. To be on multiple platforms is likely a good way to promote myself but I don't have them setup yet. 4. is the best for ROI on earned rewards. Without them my account and I think many other red fishes would not have grown as much as it has today. All points well taken. Thanks.
