One cool thing I've seen some people do to help friends find their feet in the Fediverse is to provide them with an importable list of accounts to follow.
You can export a list of the accounts you follow as a CSV file. If you take out all the accounts that are very particular to your interests, you'll probably be left with a couple to a few dozen accounts that would be of interest to most people with interests that are broadly similar to your own. People like your friends, most likely.
If they import that list of accounts to follow, they can skip the depressing "looking at an empty feed" stage of being on Mastodon without having to figure out the most practical ways of discovering new accounts to follow.
@FediFollows should probably be on any such list, by the way. And FediFollows might want to consider an option to download a CSV file of all the accounts in any given category, as an easy way to get started with a topic.
