Hi Gubba, welcome to the community.
There are some specific issues that generate more rewards than others, but as @interpretation said, it is a generic community, feel free to post about anything you want.
One way for your post to get better curation is by posting straight from the proofofbrain front end and using the word proofofbrain as the first tag
If you have any doubts, do not hesitate to ask, and you can always mark me in any publication if you think it is necessary.
The contest that I am currently active in has a delegation of 100 POB, where the user makes a post on the topic of the week and one is drawn to win. 800 POBs have been delegated to date. If you want to check it out you can click here.
The community also has a channel on Discord, show up there.
P.s .: A clue for you. Promoting POB on your social networks can bring a great return to our community given the size of your influence on networks like instagram, twitter and tiktok. It would be content that would probably generate a high reward, we are all thinking daily about ways to publicize the community so that it has more supporters, but we don't have (at least not that I know of) someone with enough numbers for that as you have.
Thank you for the welcome Vempromundo and for the tips! I'll be using the proofofbrain front more often still getting use to the tribes and what content goes where. Glad to hear this is a place I can share everything I do :)
