This question is especially for people who have joined in the last week. Have you used other fediverse platforms or is this your first time really using one? What do you think of it so far? Are you aware that you can comment on Lemmy posts with a Mastodon account?
I created accounts on both lemmy and mastodon. I've found that I spend most of my time on lemmy, though I do find that mastodon has several good news aggregation communities that I follow. Like many other new users I'm hoping that future improvements allow for the ability to combine similar community content across multiple instances into a single feed, though I also see the advantage of keeping them separate in order to allow for different trains of thought.
