I started using nostr when I realized it is "actually" a distributed protocol, less than 2 months ago. There should be no "signup" with a good client.

The best clients just show the feed without even asking about signup (i.e. creating keys) When the user goes to post the client generates a key at the click of a button and tells the user to copy it or loose it. That is the best experience for new users. Coracle and Iris are good for this on a computer. Amethyst is very good for this on android.

For me however, the best client is Gossip because I want total control over my computer and have little trust in web tech and DNS, etc. There is something for everyone in the clients being created right now. New users should try some different ones out until you find one you like, they are all different.

Also, Recently for about 2 weeks there was an app on a site called https://member.cash that had the best interface I have seen. I found it and tested it and it was great but in two weeks it was gone and I can't find it again. (maybe NSA doing some testing?) The app was really well laid out and did everything right... best I had seen, but before I even got a chance to look for the source, it was gone. A heads up to new users, if a client works too good I would be skeptical. The developers are working fast, but the apps are far from polished at this point, any you find like member.cash that are mature and seem to be blistering fast, I suggest asking around to find out who the developer is and if anyone has examined their code.

The eruption of lighting enabled zaping of bitcoin (sending people money instead of 'likes') is nothing short of phenominal. However, new users should be and probably are VERY sceptical about using these because although the tech is solid, the trust in third parties is not. It's a lot like taking candy from strangers... be careful who you trust.
