I see people using hashtags like #nostr #bitcoin #grownostr #dogstr #coffeechain

So I figured I'd experiment and use them as I feel into using this protocol.

So can I ask, what's the main purpose of hashtags on here?

I am only guessing it categorizes your notes so people sorting through to view content in just those hashtag categories see you? What else?

What are your favorite or regularly used hashtags?

What more should I know about #hashtags on #nostr?
