I have been playing with raspiblitz LN node for ~2 years. I got to relatively high ranking routing node, but it was quite a journey to set up + up to 1h a day job, just to sustain that and I earned a few sats... If you want to run LN node just for yourself (and your rl friends) to zap on nostr then it would be quite easy and comparable to running small wot nostr relay (but I am not sure if there is such implementation yet) - if you have some Linux sysadmin skill of course - my brother was running umbrel LN node with no sysadmin skill - just google/ai though If you want to run routing LN node and be profitable - it is difficult because of the issues with managing liquidity. But running public nostr node is probably more difficult due to bots and it is also difficult to be profitable.
