1. Is there a benefit to creating posts in multiple communities? So many Nerds share posts from multiple communities.

2. I read a post by @gadrian titled How to Improve Your Curation If You Have Low Hive Power which says

What you should do instead is to vote on the post(s) instead if they are above the dust threshold or you believe they will be. And within the first 24 hours. No need to slash your curation rewards unnecessarily by voting after the first day.

Is it true you should not vote after the first 24 hours?

Thanks for all you do.
