Free and Open Source software. I don’t mean anything specific, but if you use/need software it doesn’t hurt to search if there are any FOSS solutions available that suit your needs. If it does, you might save a couple of bucks. If it doesn’t you can still use your proprietary solution anyway.
I agree. I’m still hoping some subreddits will move over to Lemmy, but I’m really enjoying Lemmy anyhow. The Lemmy communities seem generally really positive so far and there is enough content for me to enjoy. It even helps with reducing my time lost on the internet while still providing me with the community and information-influx that I enjoy. Quality over quantity. I also really love the idea of the technical parts: federated, open source and self-hostable.
