If you can, stay patient :) if you can’t bear how it’s empty, I say it’s totally fine to go back to reddit or use both!
For me I’m usually selecting Show the feed of all communities, since I’m realizing there’s new content across the fediverse maybe every 30min to an hr, rather than like on reddit tons every second.
I find every post being made has a lot of engagement and fun convo - especially about reddit migration - so at the moment I tune into everything.
Just now there was a new post from the Memes mag, and earlier I saw some from foodporn
