Fediverse

i've been playing around with a self hosted lemmy instance for a bout a week so far and loving the whole fediverse concept so far. I'm thinking about also putting up a mastodon instance to see how the micro-blogging is. but i've run into some other projects that sound interesting too. so i'm looking at Friendica with the idea of a single feed to cover many sources (mastodon, lemmy, rss, other federated protocols). i haven't seen it mentioned much or some of the other projects either. are there any downsides to using this approach, instead of a dedicated instances.
