I use Nostr to be social. That includes talking to old and new friends, community building, content creation, and interacting with as many people as possible. I love trying new clients and seeing what new applications have to offer, but I mostly stick to the same ones.
For general use as a daily driver, Amethyst is by far my most used client. It used to be Snort though. I prefer desktop clients, because I love to multitask, but no desktop client functions well for me any longer. I do use Primal and Nostrudel from time to time.
Into the realm of Other Stuff, I'm using Highlighter, Nostr Nests, Zap.stream, and Wavlake, on a weekly basis.
