Case in point, they created a 2nd channel: nostr:nevent1qqsxqcwvrm8ly4k9662qjha25wzdu8a0k3q4g03f7rkrp72p2gdesqgpr9mhxue69uhhyetvv9ujumn0wdmksetjv5hxxmmd9upzpd7x76g4e756vtlldg0syczdazxz83kxcmgm3a3v0nqswj0nql5pqvzqqqqqqy6n8zh9  

 You don't need new profiles if you can just publish in different communities and manage those. 
That way things can overlap (as they always do).

You can post your Freedom Tech articles in the communities most suited for them and your insights on Photography in a completely different set of communities. And you can publish your article on a Nostr app for photographers in a selection of both of these niches of communities. 

Without settting up a new profile.
With different prices & guidelines for each community.

And with something the internet never had before: 
The members of your selected communities for your post all come together and meet around that post. One event ID, one reply section accessible to all these members. 
 

 That's true in most cases, and I hope we'll get there with nostr. But it has its limits too. That's why some people are just "Steve" for the long weekend in Las Vegas.  

 Yup haha, you 💯  need the "Steve" npubs too 😂 . 

You just really don't need them for every niche topic you want to publish content about.
