Yes, it was not the most tactful introduction. I, for one, am glad you're here.

Another good way to verify your nostr account is if you own a domain with a well-known website you can add your encoded npub there. It's called a NIP-05 identifier and it gives you a nice human-readable handle on your profile.

For example, here are the NIP-05 identifiers I have set up for some of my peeps. https://trianglebitdevs.org/.well-known/nostr.json

You'll need to add a file at [YOUR_DOMAIN]/.well-known/nostr.json with a short identifer (maybe "efrat" or "efinigson" to match your twitter handle) and your hex-encoded npub address. Yours is 6a359852238dc902aed19fbbf6a055f9abf21c1ca8915d1c4e27f50df2f290d9 which I found here by clicking "show more details" https://njump.me/npub1dg6es53r3hys9tk3n7aldgz4lx4ly8qu4zg468zwyl6smuhjjrvsnhsguz 

 Thx for that. Is my tweet not sufficient? 

 It is. Welcome to Nostr. 👋 

 It is sufficient for proof but not visible unless you direct people to it. A NIP-05 identifier is visible in your nostr profile (so people don't have to open up twitter) and leverages the trust you have built around your website. Using a paid service like nostrverified.com is pointless, IMO, because anyone can pay $5 to impersonate you. It's a bit harder to steal or hijack someone's web domain, though certainly not impossible.

You could also just do nothing and that's totally fine as well. Some people on the internet (rudely) demand authentication. But people make all sorts of demands that you are not obligated to satisfy. 

 Another small improvement might be to include your npub in your twitter profile to make it easy for people to find you. Although this probably has or will be used against you by the algorithm. Elon has done it in the past in an attempt to prevent people from leaving his network, maybe still active.
