I probably wouldn't use it directly (because if people I know have joined the Fediverse, it's usually either that I met them there or I was the one who made the join 😅)

But I'd still sign up to make things easy for other people whom I get onboard, so that *they* can easily find new users the way they're used to 🔍

(In fact it's the same reason I've registered my number on #Quicksy for #XMPP folks)
