You can now get reddit posts on lemmy via RSS, without any ads ;)
Check out !worldnews@lemmit.online. The admin of lemmit.online has set up a bot that fetches reddit posts via RSS, making it much easier to make the switch and of course not getting any ads.
Also, these posts can then be cross-posted to help us create more content on lemmy native communities. Although I do recommend removing most of the post body when cross-posting. Alternatively you can turn the cross-post into a native post as if you simply were sharing content that you've seen on reddit, but with the perk of not having to load reddit.
Oh, there's a Home Assistant crossposter on Lemmit too at !homeassistant@lemmit.online . Without Reddit or Twitter I have felt very out of the loop on Home Assistant
