I’m a nurse and reddit has a nursing subreddit I like to contribute to because they give good advice regarding my job, how to deal with arrogant doctors, removed coworkers… they know things a regular user in a generic channel couldn’t answer, because they don’t know the job.
I think asking in a channel like this for nursing advice doesn’t make much sense, because this is not a nursing specific channel.
Something similar happens to my workplace questions: there is an antiwork lemmy, but the one in reddit is much larger and they also have a work community, and so far I haven’t found anything like that on lemmy.
Another issue is size: For some problems, like violence in the hospital I need speedy advice and I get that faster when the communities are larger. Reddit is larger.
Simply replying ‘we don’t monetize’ while true and one reason why I turned to lemmy and don’t use reddit as much now, is not convincing enough for my particular case.
I’ll tell you my approach and you can use it for inspiration, but keep in mind everyone is different.
I deleted the Reddit app, but still use Reddit sometimes through the browser. This caused me to use Reddit far less, and primarily use lemmy unless what I need is not found on lemmy.
Sometimes what I need is info from a specific community like you mentioned. For example, I am Arab, and there’s very few Arabs on lemmy.
In your case, Reddit might be less rare than me. It might be more practical for you to use both apps, or maybe just not use lemmy at all. It all depends on your priorities and what you’re looking for.
