+
+## Questions and Answers
+
+### Why so many accounts?
+
+In my opinion it's preferable to have multiple accounts on different homeservers for ensuring decentralisation instead of having a single authority in power and being able to issue commands from multiple servers in case of federation meltdown which multiple rooms experienced during the period of room version 9 before homeserver software started to nag on unintentionally open registration refusing to start.
+
+### Why do you use Matrix URI scheme instead of matrix.to?
+
+I dislike matrix.to as a concept. It's a centralized service on decentralized protocol and in my opinion it shows lack of self-esteem on Matrix side considering neither XMPP or IRC require something like it, both of those trust being known or handled appropiately.
+
+### Which client do you recommend?
+
+The one that fits your needs. Personally I mix-and-match:
+
+* FluffyChat on mobile
+  * I am a Finnish translator and moderator. It does multiple accounts.
+* hydrogen.element.io PWA mainly on mobile, sometimes on desktop
+  * It's the only Matrix client that is yet to log me out randomly, very stable, multiple account support and so far the only Matrix client running on Nokia 1 (TA-1047).
+* develop.element.io / Element flatpak on desktop
+  * `/devtools` is essential (see my critiques), and they don't support Fedora.
+* Nheko nightly flatpak on desktop
+  * I am a Finnish translator, it's actually the most Spec-complete client in my experience without long delays before something becomes supported and it's lightweight probably for being a native app instead of Electron.
+
+### Which homeserver do you recommend?
+
+I am hesistant to recommend any. Finnish users may be interested in the [Linux.fi wiki listing](https://www.linux.fi/wiki/Matrix), everyone else may be served by [joinmatrix.org listing](https://joinmatrix.org/servers/).
+
+### Why don't you run your own?
+
+As can be read between the lines from my critiques, I don't consider any homeserver to be in the state that it's either safe to run legally or lightweight enough or not require constant maintenance as opposed to IRC which I do selfhost.
+
+The world situation in general discourages me from anything as heavy.

+*The lucky Matrix number is `{{site.matrixLatestRoomVersion}}`, but do [consult the Spec for that](https://spec.matrix.org/latest/rooms/#complete-list-of-room-versions) and definitely ask `!servers upgrade {{site.matrixLatestRoomVersion}}` from [Version Checker](matrix:u/version:maunium.net) or [Fluff Generator](matrix:u/+:jae.fi) or [their siblings](https://github.com/maubot/rsvc).*
