If you delegate to the projects I mentioned, they will send you a share of the curation rewards they receive.

If you want to auto vote, then I think that https://hive.vote/ is a decent option.

That’s a good idea about automating your posts to be tweeted, but I’m not sure how to do it. Surely it’s possible. I can’t tell you a bunch of devs who would know how off the top of my head, but I feel like @themarkymark may know. Maybe try to ask him on one of his future AMA posts, he does them all the time and always replies.
