The one account for all thing is often mentioned as a 'selling point', and as of now I think it's rather ill-advised, setting up disappointment & possibly obershadowing a couple of nice things in that regard. A rather smooth part of the fediverse is that for example comments you read may stem from a lot of different corners, and writing one of those should work fine.

Regarding number of accounts you could experiment with a min or max approach first and then adapt based on your needs and experiences. You could re-use the first half of your handle, as the comment about identity suggested.

Discs from libraries!

Thank you, I very much appreciate that offer! I'll continue to look out for people interested in sharing the work and your advice would help a lot then!

Thank you for the link! I think both do and will co-exist allright. I think sooner or later there will be a German instance, so I'm rooting for sooner and for a solid foundation (like feddit.org) rather than a strenuous & vulnerable one person effort (like feddit.de...)

Zunächst mal bin ich der Herr Laymann, den du siehst... ;-) Aber ja, andere Unterstützung als technische geb ich gerne!

Feddit.org is great! But for some (potential) communities Piefed's flairs and tags are really great, for example. I think something like that is planned for Lemmy 1.0, tho.

Just recently heard about Snowflake browser addon for sharing bandwith

I think it's ok. Sometimes people forget that the first mastodon paragraph becomes the post title and these involuntarily bloated titles look odd.

It also would be great if following a community via Mastodon would mean receiving new posts only instead of comments too, which is annoying at least with active communities. (I mean it would be, I just don't follow them there)

I'd see the new community as a transit space in the middle

After a very quick search I don't see a community for that purpose and the whole fediverse yet. The general fedi comms and the specific !NewToPiefed@piefed.ca and !NewtoLemmy@lemmy.ca could be linked there.
Maybe I'm overlooking something outside of Piefed and Lemmy?

I didn't know it either and it's avoiding not enough/too much information nicely. For me the cherry on top would be a link to a kind of 'No stupid questions'-Community for interested or new users.

Thank you for the hint and your work! I will look into it very cautiously.
